Laser system with multiple wavelength diode pump head and associated method

A laser system having a predefined range of operating temperatures, the laser system comprising:

• 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;
• wherein the wavelength of light emitted by each respective laser diode is 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 varies within the predefined range of operating temperatures.

A laser system having a predefined range of operating temperatures, the laser system comprising:

• a reflective chamber capable of housing a laser medium, the laser medium having a peak absorption wavelength;
• and
• at least two laser diodes emitting light at different respective wavelengths into the reflective chamber;
• wherein the wavelength of light emitted by each respective laser diode is selected such that the wavelength of light emitted by at least one laser diode is displaced from the peak absorption wavelength at all temperatures within the predefined range of operating temperatures,
• wherein the reflective chamber has a hemi-cylindrical shape, and
• wherein the laser medium is located on a flat inner surface of the reflective chamber and the laser diodes emit light into the reflective chamber through at least one elongated opening in the reflective chamber, the elongated opening having a long axis that is aligned with a long axis of the reflective chamber.
