**big**10,000 mw 2 coherent lasers red green blue ar/kr
Here's a Coherent 920 laser system with TWO LASERS under the hood, a Krypton Ion laser producing 3000+ Milliwatts of RED laser light, AND an Argon Ion laser producing 7500+ milliwatts of BLUE AND GREEN laser light, or 5000+ milliwatts of GREEN laser light. Included is an optics bench for beam control, remote systems control panel and schematics for customizing to your application.
On consignment. Available for pick-up at storage location.
BELOW: Under the hood, about 10,000 milliwatts of producable laser light from the two side-by-side plasma tubes shown. Coherent really over-engineers lasers from this era. Gas refillable. Both tubes have intact vacuum and gas, and power supply and interlocks operate. In the foreground, the optics bench for control of beam selection. One laser operates at time, although they both can be in standby mode, for near-immediate access to the other colours.
BELOW: Note the Optic Bench with solenoid controlled beam selectors and interface to scope output, if desired. Use without external scope (not included), for applications such as light shows where beam access is desired to be interfaced in CDRH-approved manners, requires bypass of interlocks.
Schematics supplied. You're on your own on that.
BELOW: with the front panel down, accessing the water-cooled electronics.
BELOW: The card cage and control electronics.
BELOW: The hour meters. Laser tubes of this era, if currently in operating condition,
such as these, often run upwards of 12,000 hours.
BELOW: one of the perfect condition, pristine Brewster windows, showing tube integrity.
BELOW: The Argon and Krypton warning labels.
BELOW: The other Brewster Window, again demonstrating tube seal integrity.
BELOW: The power supply controls. Beam selection controls are on the portable, umbilicaled Remote Control, pictured below.
BELOW: Laser Selection, Power, On-time (can be bypassed for continuous operation. Schematics supplied. ) The key is lost, so the keyswitch (bottom left corner) had to be removed and bypassed.
BELOW: The electrical supply requirements: 3 phase 208 VAC, 35 Amperes. Internal bucking/boosting transformer allows acccomdation of input voltages of approximately 185-240 VAC.
Termination is in bare 4 wire.
BELOW: Due to the power of this laser system, it requires water-cooling of both the plasma tubes and the transistorized current passbank. Below are the hoses (conventional connections) supplied. A filtered supply of approximately 2.2 gallons per minute or 45 PSI, and a suitable drain for low pressure, 1 gallon per minute is required.
Custom crating can be available for additional cost, please inquire.
This item is ON CONSIGNMENT so is available for pick-up at its storage location.
CONDITION: this unit has been recently checked out fully by an independent electronic repair facility with 40+ years experience. All functions are fully working to original manufacturer specs.
