Nd:GdVO4
Nd:GdVO4
Nd:GdVO4 is one of the most efficient laser host crystals currently existing for diode pumped configuration . Its large stimulated emission cross-section at lasing wavelength, high absorption coefficient and wide absorption bandwidth at pump wavelength, good thermal conductivity, high laser induced damage threshold as well as good physical, optical and mechanical properties make Nd:GdVO4 an excellent crystal for high power, stable and cost-effective diode pumped solid-state lasers.
Advantages:
◆ Good Thermal Conductivity
◆ Lower lasing threshold and higher slope efficiency
◆ Large stimulated emission cross-section at lasing wavelength
◆ High absorption over a wide pumping wavelength bandwidth
◆ Low dependency on pumping wavelength and tend to single mode output
◆ Optically uniaxial and large birefringence emit strongly-polarized laser
Nd:GdVO4 crystals is the idle substitute of the Nd:YAG and Nd:YVO4 crystals for the high power DPSS laser. Comparing with Nd:YVO4, Nd:GdVO4 has good thermal conductivity and can offer better property to get high power output . Comparing with the Nd:YAG, Nd:GdVO4 has higher a lot slope efficiency, the more compact design can be available.
With advanced technology on growing high optical quality and large size Nd:GdVO4 crystals, NEWPHOTONS steadily provides as large as f25 x 40 ~ 60 mm3 Nd:GdVO4 bulk crystal, Now, NEWPHOTONS massively produces and provides high quality Nd:GdVO4 crystals at very competitive prices
