Solid State Nd YAG Laser Rod - Low Threshold Pulse CW Operation Industry
Description

Neodymium doped Yttrium Aluminum Garnet (Nd:Y3Al5O12 or Nd:YAG) crystal, which continues as the best of the rare earth garnet materials that are characterized by four-level laser operation which permits low threshold pulse and CW operation. It is the most mature and widely used solid-state laser material adopted by R&D, medical, industrial and military customers. Its main and obvious advantages are: high gain, low threshold, high efficiency, low loss at 1.064 m, as well as high optical quality, good thermal conductivity and thermal shock characteristics, stable chemical and mechanical properties, which make Nd:YAG as the most suitable and commercial laser material for various modes of operation (CW, pulsed, Q-switched, mode locked and cavity dumped).

Features

Wide absorption bandwidth

Low lasing threshold

High slope efficiency

Large luminescence cross-section

Linearly polarized emission and single-mode output
