YAG Laser System Concept
|
The 4000 Series
Industrial Laser Systems are
designed to perform demanding, precision laser processing tasks
in a production environment. The
Nd YAG Laser System combines accuracy and precision
with stability and ruggedness for many applications including
micro-machining, precision welding, scribing, drilling, resistor
trimming, soldering, and ablation.
|
|
The 4000
Series YAG Laser System
is conceived as a set of standard building blocks, which are
combined to optimize performance for specific process and
environment.
The major building blocks are the
Nd YAG laser, beam delivery
optics, motion control, and frame structure.
|
Industrial Laser
|
|
The
industrial
laser is selected
from U.S. Laser's wide range of lamp pumped Nd:YAG lasers
or from diode pumped Nd:YAG or Carbon Dioxide offerings from
Lee Laser, Spectra-Physic, Coherent or Synrad. |
|
The Table below lists
the range of available U.S. Lamp pumped Nd:YAG lasers with
power levels and typical applications. |

Laser
Beam Delivery Optics
|
The conventional optical system in the
4000 Series YAG laser system
combines diffraction limited laser
beam delivery with high resolution coaxial and parfocal CCTV
viewing. This industrial laser
system design (incorporating upcollimator, objective lens, and
camera lens) allows for independent selection of spot size, working
distance, and image magnification.
|
|
The heart of this
industrial laser system is a series
of high-aperture multi-element apochromatic lenses designed
exclusively by U.S. Laser.
Fiber optic and galvanometer beam
delivery systems are also available. |
Industrial Laser
Equipment: Frame Structure
|
For rigidity and stability in
industrial environments, the 4000 Series
YAG Laser System is integrated
in a welded steel box tubing frame, with tooling plates supporting
the laser rail and the workpiece area. Cleanliness of the
optical components is maintained by hinged covers and an air
filtration system.
|
|
C.D.R.H. Class I
laser systems include a workpiece area enclosure.
The enclosure includes a large sliding access door with laser-safe
viewport, internal illumination, and a baffled exhaust port. |
YAG Laser System:
Motion Control
|
|
The 4000 Series
Industrial Laser System is available with 2D and 3D
processing capabilities. Two dimensional XY systems include moving
table, moving beam overhead gantry and split axis with range of
motion up to 3 ft. x 6 ft. |
|
For 3 dimensional processing, XYZ
systems can be supplemented with rotary and tilt axes. |
