Abstract： |
An angle pump method and its solid laser gain module used in strips is to apply an angle pump structure in which the pump light source is put at the corners of the strip, so the pump light will emit into the strip from its corner plane. Center of the strip contains one or more doped areas and the surrounding linking are not doped. Most of the pump light is restricted in the strip absorbed many times due to the complete reflection, so as to get a rather long absorption length and high absorption efficiency. Strips are in the structure of doped at the center not doped around to ensure the pump light is absorbent at the strip center, reducing thermal lens effect and stress birefringence effect, avoiding strip distortion. |
