Nd:YLF – Laser Crystal – Gain Medium – Customized Products
Nd: YLF crystal product, also known as neodymium doped lithium yttrium fluoride, is a laser crystal product with excellent comprehensive performance. Nd: YLF in mode-locked laser, continuous excitation. It is widely used in the field of light and material processing. Neodymium: lithium yttrium fluoride (Nd: YLF) is an alternative medium of Nd: YLF, which is used to work in the near infrared and-Laser is generated at 1047nm and 1053nm. When the pump wavelength is 808nm,Nd: YLF can be pumped by lamp and diode. The product has a large fluorescent linewidth, low thermal lens effect, natural polarization. The main advantages of nd: YLF are that the laser has a relatively long fluorescence lifetime at -1047nm and 1053nm, and produces Generate high pulse energy. It can be used in linearly polarized resonators, mode-locked lasers, diode-pumped Nd: YLF lasers, Ti: sapphire chirped pulse amplifiers Products. In addition, the gain and emission wavelength of Nd: YLF is related to polarization: π polarization is strong at 1047nm, σ Polarization is lower at 1053nm Weak. The 1053 nm line is very suitable for the gain peak of Nd: glass, so the Nd: YLF laser is usually used as the Nd: YLF laser generator and subsequent preamplifier of Nd: glass amplifier.
