Nd-YVO4 CRYSTALS

The Nd:YVO4 crystal is one of the most efficient laser host crystals currently existing for diode laser-pumped solid-state lasers. Its large stimulated emission cross-section at lasing wavelength, high absorption coefficient, and wide absorption bandwidth at the pump wavelength, high laser-induced damage threshold as well as good physical, optical and mechanical properties make Nd:YVO4 an excellent crystal for high power, stable and cost-effective diode-pumped solid-state lasers. Developments have shown that Nd:YVO4 can produce powerful and stable IR, green, blue lasers with the design of Nd:YVO4 and frequency doubling crystals.

The Nd:YVO4 lasers possess the advantages of lower dependency on pump wavelength and temperature control of a diode laser, wide absorption band, higher slope efficiency, lower lasing threshold, linearly polarized emission, and single-mode output. For the applications in which more compact design and the single-longitudinal-mode output are needed, Nd:YVO 4 shows its particular advantages over other commonly used laser crystals. The diode laser-pumped Nd:YVO 4 compact laser and its frequency-doubled green, red or blue laser light will be the ideal laser tools of machining, material processing, spectroscopy, wafer inspection, light show, medical diagnostics, laser printing and the most widespread applications.
