摘要： A laser resonator comprises a cylindrical gain medium, a cooling system and a coupling member. The cylindrical gain medium comprises a central axis, an outer side surface, two opposing end faces and a first depression in the outer side surface. The cooling system comprises a cooling jacket disposed around the gain medium that defines a cooling cavity, in which cooling fluid is guided over the side surface of the gain medium. In one embodiment, the cooling jacket comprises a second depression. The coupling member is received within the first and second depressions. Movement of the first depression along the central axis relative to the cooling jacket is restricted by the coupling member.

摘要： A pump module comprises a power source, a plurality of laser diodes, a controller and light combining optics. The laser diodes each have an activated state and a deactivated state. The laser diodes receive current from the power source and output light when in the activated state and do not receive current from the power source when in the deactivated state. The controller switches the plurality of laser diodes from a first power mode, in which a first subset of the laser diodes is in the activated state, to a second power mode, in which a second subset of the laser diodes is in the activated state, responsive to a power mode setting. The light combining optics are configured to combine the light from the activated laser diodes and output the combined light as pump energy.A laser system comprises a pump module and a gain medium. The pump module is configured to output pump energy having a wavelength that is within a wavelength range of 874-881 nm. The gain medium is in the path of the pump energy and is configured to absorb the pump energy and emit laser light responsive to the absorbed pump energy. In one embodiment, a controller switches a power level of the pump energy between first and second power levels responsive to a power mode setting input from an operator.
