Nd:YLF


Nd:YLF is an excellent crystal for mode-locked operation due to its low thermal lensing effect,large fluorescence linewidth and linearly polarized light beam output.

Classification:


Nd:YLF is an excellent crystal for mode-locked operation due to its low thermal lensing effect,large fluorescence linewidth and linearly polarized light beam output.

 

PRODUCT FEATURE

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.

Large rods and slabs can also obtain uniform mode laser output.

It is suitable to be used as oscillator and preamplifier of high power Nd:Glass laser system.
