Nanosecond laser 355nm is a kind of special laser which can produce laser of the wavelength of 355 nanometers in very short time. It is usually used in scientific research, medical treatment, industrial manufacturing and etc.
355nm nanosecond laser adopts frequency doubling technology that shorter wavelength of 355nm laser is obtained by doubling the frequency of longer wavelength lasers through crystals. The most commonly used material of frequency doubling is β-BaB2O4 (BBO) crystal. The crystal has good nonlinear optical properties which can convert solid state lasers such as Nd:YAG or Nd:YVO4 of 1064nm or 532nm wavelengths into short pulse lasers of 355nm wavelengths.
