Zenghu Li output power that can be attained with a medium of a certain length. For solid state lasers this limit is caused by the pump induced thermal heat .. which has to stay below the fracture limit to avoid damage to the active material. For a laser rod the maximum output power .. per length is given by:

Zenghu Lipower of stable resonators. In the resonator model used (Fig. 10.1) it is assumed that both the forward travelling beam with intensity ..(.) and the backward traveling beam with intensity ..(.) cover the same area of the active medium. The complete overlap of the two counterpropagating beams is char
