Nd YAG Laser - Industrial Laser System
4000 Series YAG Laser Systems
with multi-axis motion
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 typically selected from U.S. Laser's wide range of diode pumped, lamp pumped, continuous wave (cw), pulsed, Q-switched lasers. If a particular application requires the performance of a different type of laser, such as vanadate lasers or fiber lasers, U.S. Laser can build your system using appropriate lasers from other manufacturers.
|
The Table below lists the range of available lasers that are standards of U.S. Laser manfacture. Special features can be provided. And, where appropriate, lasers of alternate sources can be provided. |

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.
