selling 2 Nd:GdCOB crystals

[Sowee7]

hello everyone, i am selling 2 Nd:GdCOB self doubling crystals that have hr and oc mirrors coated on them. these crystals lase at 545nm when pumped with a 808nm or 796nm pump diode. Pm me if you want one

How much pump power can these handle?

Does anyone know if these crystals are hygroscopic?

ive tested them with 500mw, im not sure if they can handle more.

i dont really know if they are hygroscopic, ive had them for a few weeks and i have had no problems with power.

no one wants to buy any?

I'm tempted but I've got too many other projects right now. If I was sure these weren't hygroscopic I'd bite but I don't want to have one sit for a year and be ruined by humidity before I get to it.

"The GdCOB crystal has also very interesting physical properties because it melts congruently and is not hygroscopic."

Self-frequency doubling of the 936-nm line in Nd:GdCa/sub 4/O(BO/sub 3/)/sub 3/

Summary form only given. Nd/sup 3+/:Ca/sub 4/GdO(BO/sub 3/)/sub 3/ (Nd:GdCOB) is an efficient laser material in the infrared under Ti:sapphire and diode pumping. Moreover self-frequency doubling of the laser line has been observed with crystals cut for phase-matched second-harmonic generation...
