Abstract
An exemplary laser system is disclosed which includes a pump laser diode array and laser gain material, in which the array generates optical radiation having a predetermined total linewidth approximately 20 nm wide constructed from a plurality of individual wavelengths with a linewidth of up to 8 nm, the center wavelength of radiation being for example within the absorption band of laser gain material used at the center point of the operating temperature of the array. The system can include a highly reflecting plane mirror with periodic transmitting patches placed between the laser diode array and the laser gain material, the size of the transmitting patches being such that minimal pump radiation is lost.
