Lexel Laser Model 65 Laser System (Gallery)
The Lexel Model 65 is one of the few Lexel air-cooled ion lasers (most are
larger and water-cooled). It is capable of about 165 milliwatts blue/green
(488 nm) single mode. It operates from standard 115 VAC, 20 amp service. The
power supply is a very reliable, series regulating design. Original cost
was over $9,000.00 some years ago. This is a superb air cooled laser, built
like a tank.

Lexel Laser Model 75 Laser System in Operation (Gallery)
The Lexel Model 75 is a small water-cooled laser, a baby cousin to the Lexel
Model 88. It operates from a standard 110 VAC line so you don't need to own
stock in your local utility to be able to afford the electricity bills. :)
Though the output power rating of the Lexel-75 is 100 to 300 mW, some of these
babies will do 450 mW when new. Because of the better cooling, they will last
a lot longer then their shorter air cooled brethren.

- Lexel Laser Model 88A Laser Head (Gallery)
This is a nice clean sample of a model 88A laser head. The original model
88 could do 2 W - don't know about the 88A.

Lexel Power Supply for Model 88 Laser Head (Gallery)
The Lexel Model 88 can produce up to 2 watts or more but requires 220 VAC
at up to 50 A or 208 VAC three-phase! Unfortunately, all we have at the
moment is a photo of the power supply front panel.
