Coherent Avia 266-3000 266nm 3W DPSS Laser

Description

This auction is for a Coherent Avia 266-3000 266nm 3W DPSS Laser.
This laser in not producing 266nm UV.  I suspect the FHG crystal is damaged and needs replacing.  These lasers need constant power to keep the crystal in good condition.  There is an internal battery to power the crystal heater.  The battery needs replacing.
The laser has only 1700 hours use on the laser diodes.  I tested the 808nm pump diodes and they produce in excess of 30 watts each.  They are probably producing more but I could not get my power meter close enough.
All of the temperature settings (Servo) lock including lasers rods/ laser diodes, SHG/FHG crystals.  The crystal positions have had minimal use.
Laser head has not been opened, and contains factory stickers.
Please ask if you have any questions.
Buyer to pay Freight shipping.  I will crate and get ready to ship at no cost.
Thanks for looking!
