Nd:YVO4 3*3*4 for a Viasho 1W head

[shrad]

I have burned my first crystal

I was wondering what the hell was that yellow-orange glow I could see in the crystal through my OD-5 glasses (tiny tiny cone of light orangey glare)

Now I know this is vanadate heated to near-burning temperature and that once a fly farts in tumbuctu, it flashes...

Luckily enough it was an old head and I was statring to have a look at realigning it, this was the probable cause of drop in power...

So to the question, who has a suitable vanadate for a 1W green head? Dimensions are 3*3*4mm but I need to check back to be sure

Thanks all!

I've got a bunch of 3x3x4mm Nd:YVO4 crystals here with 0.5% doping. These are pulls from Iris Medical (now Iridex) machines that made around 3W green using a 15W pump diode. One end is HR532. The other end is AR808 and may also be HR1064. Not sure if that's suitable for your laser but I'll give you one for the cost of shipping if you want to try it (and let me know what you learn about the coating on the input and).

I'm quite interested! I may check for coating reflectivity with my nanolase YAG at 1064nm

I'll send you a PM with what you need
