ABSTRACT:
A laser system comprises a reflective chamber capable of housing a laser medium and at least two laser diodes emitting light at different respective wavelengths into the reflective chamber. The wavelength of each respective laser diode may be selected to minimize fluctuations in absorption by the laser medium of light emitted by the diode bars as the wavelength of each respective laser diode changes due to changes in an operating temperature of the laser system. The wavelength of each respective laser diode may be selected such that absorption by the laser medium of the wavelength of light emitted by one laser diode increases and absorption by the laser medium of the wavelength of light emitted by another laser diode decreases as the operating temperature changes within a predefined range.
