2%nd:YVO4 3X3X1MM3+ ktp 2X2X5MM3 laser crystal set
Nd:YVO4 is the most efficient laser host crystal for diode pumping among the current commercial laser crystals, especially, for low to middle power density. This is mainly for its absorption and emission features surpassing Nd:YAG. Pumped by laser diodes, Nd:YVO4 crystal has been incorporated with high NLO coefficient crystals (LBO,BBO,or KTP) to frequency-shift the output from the near infrared to green, blue, or even UV. This incorporation to construct all solid state lasers is an ideal laser tool that can cover the most widespread applications of lasers, including machining, material processing, spectroscopy, wafer inspection, light displays, medical diagnostics, laser printing, and data storage, etc. It has been shown that Nd:YVO4 based diode pumped solid state lasers are rapidly occupying the markets traditionally dominated by water-cooled ion lasers and lamp-pumped lasers, especially when compact design and single-longitudinal-mode outputs are required.
Nd:YVO4 s advantages over Nd:YAG
* As high as about five times larger absorption efficient over a wide pumping bandwidth around 808 nm (therefore, the dependency on pumping wavelength is much lower and a strong tendency to the single mode soutput)
* As large as three times larger stimulated emission cross-section at the lasing wavelength of 1064nm
* Lower lasing threshold and higher slope efficiency
* As a uniaxial crystal with a large birefringence, the emission is only a linearly polarized.

Diode pumped Nd:YVO4+KTP green laser.
* 8W green laser was generated from a 15W LD pumped 0.5% Nd:YVO4 with intracavity KTP.
* 200mW green outputs are generated from 1W LD pumped 2% Nd:YVO4 lasers by using 2x2x5mm KTP and 3x3x1mm Nd:YVO4
* 2-5mw green outputs are generated from 180mw LD pumped 3% Nd:YVO4and KTP glued crystals.For more details,please refer to Glued Crystals
