Nd:YVO4 Crystal

 

 
Applications:

Nd:YVO4 is suilable for diode pumping among the current commercial laser crystals, especially for low to middle power density. 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. Nd:YVO4 has widespread applications of lasers, including machining, material processing, spectroscopy, wafer inspection, light displays, medical diagnostics, laser printing, etc.

Advantages
 
Lower lasing threshold and higher slope efficiency
High absorption over a wide pumping wavelength bandwidth
Low dependency on pumping wavelength and tend to single mode output
Large stimulated emission cross-section at lasing wavelength
Optically uniaxial and large birefringence emit strongly-polarized laser
Linearly polarized light output, easy tuning for single mode and high tolerance for pumping wavelength
