Welding

Laser welding offers a variety of benefits over other types of welding: deep penetration of precise narrow welds, small heat affected zone, low heat input, fast weld times, minimum part distortion, no secondary processing and high repeatability. Many metals can be welded including stainless steel, carbon steel, titanium, aluminum and dissimilar metals.  

When defining a weld joint we refer to both the joint type and the weld type. There are two joint types: butt and lap. A butt joint is where two materials are to be welded at the seam that forms where the two materials are joined together. A lap joint is where two materials are to be joined by welding through one into the other. There are also two weld types: seam and spot. Seam welding is continuous while spot welding is intermittent. Glass sealing and glass-to-metal sealing is also accomplished with Nd:YAG lasers. Plastic welding with Nd:YAG lasers has been in development for some time and is now commercially viable with certain plastics.

Products:  U.S. Laser designs and manufactures both High Power and  Low Order CW Multimode, Pulsed laser welders, and Turnkey welding systems. CW welders are excellent for producing continuous seam butt welds. Pulsed lasers are good for lap welds and spot welding.


Cutting:

In laser cutting, focused laser light is used as the heat source to both melt and vaporize material in it's path. Many metals can be cut precisely with a laser by varying power, feed rate, spot size, and gas type and flow. Laser cutting is fast, flexible and cost effective.

Products: U.S. Laser designs and manufactures  High Power CW Multimode lasers and Pulsed lasers for cutting, as well as Turnkey cutting systems for cutting many metals up to 1/4 inch thick.


Drilling

Laser drilling is the process of removing material to create through holes. Drilling can be done by percussion or trepanning. Percussion drilling focuses the beam to a spot equal to the diameter of the hole to be drilled. If a large hole is required, the laser is moved with respect to the work piece to form the desired diameter. This is called trepanning. Laser drilling is ideal for high production volumes. It is cost effective, and has no drill breakage or tool wear. Nd:YAG lasers have the ability drill unlimited hole sizes and shapes in a variety of materials including most metals, ceramics, and semiconductors.

Products: U.S. Laser designs and manufactures Pulsed lasers, Q-Switched TEMoo Mode lasers, and Frequency Multiplied Q-Switched TEM00 Mode lasers for drilling, as well as Turnkey laser drilling systems.


Micro-Machining

Laser micro-machining is used to produce very small parts or very small features in parts. It is similar to cutting and drilling, but on a very small scale. Features as small as a few microns can be produced using very high peak power short pulses, but low average power. The resolution of features produced is proportional to the wavelength used and the beam quality. Materials that can be micro-machined with Nd:YAG lasers include metals, ceramics, plastics, glass, laminates and composites.

Products: U.S. Laser designs and manufactures Q-Switched TEM00 Mode lasers and Frequency Multiplied Q-Switched TEM00 Mode lasers, as well as Turnkey laser micro-machining systems. In addition, U.S. Laser manufactures laser micro-machining systems utilizing Spectra-Physics diode pumped lasers.

  • Second harmonic optics for very fine spot sizes, or especially stable temperature coefficient trims on ceramic substrates.
  • Alternative or custom measurement devices.
  • Step and repeat circuit carriers.
  • Probe platten and probe card holders.
  • Programmable relay matrix for transferring to the next resistor.

Products: U.S. Laser designs and manufactures Low Order  Q-Switched Multimode lasers and Q-Switched TEM00 Mode lasers, as well as Turnkey Systems for resistor trimming applications.


Soldering

The Nd:YAG laser is a very effective soldering tool in applications where the amount of heat introduced to the part during the process must be minimized, or where production throughput requirements dictate a very fast soldering process.

Products: U.S. Laser designs and manufactures Low Order CW Multimode lasers and Turnkey Systems for laser soldering applications.


Marking

Lasers are becoming the method of choice for marking on many different surfaces including most metals and many plastics. This is because laser marking has clear advantages over other marking technologies. Printing systems require ink usage, and hazardous solvent handling and disposal. Tools wear in stamping systems. Laser marking systems, on the other hand, offer a clean, low maintenance, easily configured system for permanent marking of surfaces. 

Products: U.S. Laser offers a range of OEM and Turnkey Nd:YAG laser Marking Systems.


Scribing

Scribing is very similar to marking in that lines or characters are produced in the material. Scribing generally refers to a process where the finished line is the same as the kerf or beam width. Semiconductor materials and ceramics are commonly scribed materials.

Products: Turnkey Systems with U.S. Laser's lamp pumped Q-Switched TEM00 Mode and Frequency Multiplied Q-Switched TEM00 Mode lasers are available. U.S. Laser also manufactures turnkey systems using Spectra-Physics supplied diode pumped lasers. U.S. Laser also supplies Marking Systems for scribing applications.


Photovoltaic Panel Processing

Nd:YAG lasers are used for creating conductive traces in a metal layer on photovoltaic panels, and for scribing panels for breaking to specified sizes. U.S. Laser has delivered numerous photovoltaic panel processing systems with large, accurate granite based motion systems.

Products: U.S. Laser has been a leader in providing laser scribing systems to the photovoltaic panel scribing industry for years. Turnkey Systems with U.S. Laser's lamp pumped Q-Switched TEM00 Mode and Frequency Multiplied Q-Switched TEM00 Mode lasers are available. U.S. Laser also manufactures turnkey systems using Spectra-Physics supplied diode pumped lasers.


Heat Treating

Lasers have the advantage of being able to heat treat precise areas of metals without involving the entire work- piece. Laser can provide precise heat input control to localized areas minimizing distortion, stress and cracking. Laser heat treating is time efficient, and provides access to hard to reach areas. The mass of the material being processed is generally sufficient for rapid heat removal or quenching. The enhanced mechanical and electrical properties resulting from laser heat treating will depend upon the composition of the metal or alloy.

Products: High Power CW Multimode lasers are used for heat treating applications like annealing and domain refinement.


Metal Deposition

Direct metal deposition laser systems are being used for rapid prototyping, repair of expensive components (like those used in aircraft engines) and manufacturing of fully dense parts for use as system components. Metal parts are built up by injecting metal powder into the focused spot of a high power CW laser beam. The mechanical properties of the finished parts are often superior to those of parts fabricated from traditional metal-working techniques. Metal deposition also allows for continuously fabricating parts from different alloys. U.S. Laser's high power CW multi-mode laser are used by Optomec Design Company in their Direct Metal Deposition System. The Optomec system uses the Laser Engineering Net shaping (LENSTM) process developed at Sandia National Laboratories.

Products: High Power CW Multimode Nd:YAG lasers are the system of choice for this exciting new field of direct metal deposition for prototyping, manufacturing and cladding.


Paint Stripping and Surface Removal

Certain paint stripping and surface removal applications are ideal for laser systems.  Lasers offer a benefit over chemical stripping applications where waste disposal, or chemical interaction with the base material is an issue.  Nd:YAG laser stripping can also be done with fiber optic beam delivery in applications where the area to be treated is inaccessible to human operators due to the hazardous nature of the environment or physical inaccessibility. 

Products:  The power/removal ratio in these applications is dependent on peak power density.  Higher peak power density results in more efficient removal.  U.S. Laser's High Power Multimode Q-Switched Lasers offer very high peak power density due to short Q-Switched pulses and small spot size achievable due to high beam quality.
