Nd:KGW or Nd:KGd(WO4) Laser Crystal is an excellent laser gain material which has low laser oscillations threshold and higher emission section.
The fluorescent concentration quench effect of the Nd3+ ion in the KGW crystal may be weakened due to the W-O covalent bond, Nd:KGD crystal has a higher doping concentration of active ion.
Furthermore, the absorption band at 808nm of Nd3+ in the KGW which has 12nm FWHM is well matched with the emission wavelength of current commercial laser diode.
Specifications of Nd:KGW:
standard dopant concentration (at .%) : 3,5,8
maximum length: 50mm
length tolerance (mm) :+1.0/-0.0
diameter tolerance (mm) : +/-0.0
parallelism: <30 secs
perpendicularity: <15 min
surface quality: 20/10
