Optics & Photonics Talk

Laser rod donation to a goodf home
William Buchman
I have some laser rods rescued from getting dumped at Hughes some years ago. They are uranium doped calcium fluoride grown by Hargreaves at Optovac. I would hate to see them dumped again when I go. It would be great if someone would want them either as artifacts or to use them. would be most happy to pass them along. If not, I would be happy for any other suggestions.

I used these rods almost 50 years ago. I used silver coated mirrors on rods with a coupling hole, just like Maiman did. IIRC they emitted at about 2.5µm. I used liquid nitrogen gas cooling. With end pumping now possible with LEDs or lasers, there might actually be a way of using them with relatively low thermal stress. These were described by Sorokin and Stevenson.

Please let me know if these are of any use to anyone or whether disposing of them is the best thing to do.
