The invention provides a diode pumping module for a laser system, including a laser rod and a diode light source for excitation of the laser rod, the diode source being constituted by at least one diode array, a dual-function optical coupler/heat conductor located on one side of the laser rod between the at least one diode array and the laser rod, and attached to the rod, which coupler/heat conductor guides the light from the diode source into the rod while adjusting the angular spread of the light and also serves as heat conductor, conducting heat away from the rod. The system further includes a dual-function heat conductor/light reflector located on the opposite side of the laser rod, and attached to the rod, which conductor/reflector conducts the heat away from the laser rod and reflects unabsorbed diode light back into the rod.

Diode pumping module

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.
