System Overview

lasers are rated from 50 to 120 Watts. They can be overpowered to up to 180 Watts,
and they all integrate RFPA and cooling in one package. Two connectors in the rear provide the
interface to control signals, power, and returns diagnostic signals and faults signals. Connector
pins and associated electronics are protected against static ESD damage. DC power is applied
to the one meter power cord.
There are no user-serviceable parts under the cover. The RF cover must be removed
according to procedure; otherwise, damage could occur. The RF cover edges are RF
sealed to the top heat sink, which makes it very difficult to slide off the cover. The laser
may not operate properly without the cover in place. There are dangerous RF voltages
under the cover that will cause serious RF burns to the skin if touched.
The lasers are waveguide lasers with a “slab” unstable optical resonator. The resulting
elliptical beam is corrected by a cylindrical lens in the black extension tube mounted to
the faceplate. This assembly is exactly positioned so that the beam direction is close to
the original elliptical beam. Removal of the cylindrical lens assembly will result in the loss
of this original alignment and will require a procedure for replacement.
The optical intensity at the cylindrical lens is VERY high (>6000W/cm
2
).
Any contamination to the optical surface could cause runaway destruction of the lens.
Do NOT burn materials close to the lens or leave fingerprints on the lens.
The cylindrical lens comes with a pink plastic cap that covers the lens for protection.
Remove this cap before applying DC power. Firing the laser through the cap WILL
cause permanent damage to the lens.
