I recently found accidentally that Susie sell KTP and YVO4 crystal at a fairly good price !
http://www.o-like.com/b2b_cplist.asp?catid=467
Dimensions for YVO4 is
YVO4<300mW 3*3*1mm Nd percent @ 2% 30$
YVO4>300mW 3*3*2mm Nd percent @ 1% 48$ +4$ shipping
also there is KTP at 26 $ but don't know the dimension at now
typical low power (<100mw) green laser pointer use 1*1*? mm YVO4 crystal
above, Nd:YVO4 from a 50 mw newish type, dunno the exact lenght(1mm?) of the Nd:YVo4, because the crystal is glued with the KTP crystal.
Dissection of a Green laser pointer
Some info about YVO4
Left Absorption Curve of 0.5% doping(Nd):YVO4 Thickness:1 mm Right doping 3%
Fluorescence Spectra Curve at 0.5% & 3 %
Nd:YVO4 crystal has a low thermal conductivity coefficient, therefore, long-in-length with low dopant level Nd:YVO4 is recommended for
high power diode laser application in order to reduce thermal lasing effects.
We just need to find costless high powered 808 nm diode to play with some green
i found also a seller of polarizing beamsplitter cube (PBS)
