Nd:Ce:YAG

Nd:Ce:YAG is an excellent laser material widely used for no-water cooling and miniature laser systems. In double doped Nd:Ce:YAG crystals Cerium are chosen as sensitizer for Nd3+ ions because of its strong absorption in UV spectral region at flash lamp pumping and efficient energy transfer to the Nd3+ excited state.

As a result, thermal distortion in Nd: Ce:YAG is low and the output laser energy is greater than that in Nd:YAG at the same pumping. Therefore it is possible to realize high power lasers with good beam quality.

Lasing wavelength at 1064 nm, laser damage threshold and thermal conductivity of the Nd: Ce:YAG crystals are the same as for Nd:YAG. It is the most ideal laser material for the air cooling lasers .It is suitable for different modes of operation (pulsed, Q-switched, mode locked) and high-average power lasers.
