Nd:YLF is a solid-state laser material that operates primarily at wavelengths of 1047 and 1053 nanometers. It is favored for its high efficiency, low thermal lensing and relatively long upper-state lifetime, making it ideal for applications in precision machining, medical procedures and scientific research.
Relatively small stimulated emission cross section
Effective single mode operation,high power and low beam divergence
The output linearly polarized laser is beneficial to get high efficiency Q-switching and frequency doubling output.
It is suitable to be used as oscillator and preamplifier of high power Nd:Glass laser system.
