Abstract
A diffusely reflective fluorescent powder used in a laser pumping cavity directs light onto a laser rod and in addition increases the spectral overlap between a pump source and a laser material. Undesirable ultra-violet radiation, which is a substantial fraction of the pump spectrum is converted into useful longer wavelength radiation thereby increasing the laser energy output. The invention further relates to a method of increasing the energy output of lasers and of laser amplifiers.
