Abstract: An array of Surface Emitting Laser (SEL) elements can be used to efficiently pump a disk or rod of solid-state laser glass or crystal, or harmonic-generating crystal. Placing the laser array chip against or near the surface of this solid-state material provides very high and uniform optical power density without the need for lenses or fiber-optics to conduct the light from typical edge-emitting lasers, usually formed in a stack of bars. The lasers can operate in multi-mode output for highest output powers. Photolithography allows for an infinite variety of connection patterns of sub-groups of lasers within the array, allowing for spatial contouring of the optical pumping power across the face of the solid-state material. The solid-state material may be pumped either within (intra-cavity) or externally (extra-cavity) to the SEL laser array.

Abstract: 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.

A second signal ν proportional to the square of the pulse power P(t), averaged over the resonator cycle, is measured for the laser emission, and the occurrence of a double- or multiple-pulse state is detected on the basis of a comparison of the measured signals μ and ν.

Abstract: Plural LDs 6 are series-connected and pump a solid-state pumping medium 7. Each of bypass circuits 15 is connected in parallel to an associated one of the LDs 6. An operation of driving each of the bypass circuits 15 is controlled by a control circuit 14. A detection circuit 13 is provided corresponding to each of the LDs 6 and detects a short circuit failure and an open failure of each of the LDs 6 according to a voltage developed thereacross or the like. The detection circuit 13 and the control circuit 14 are connected to and are controlled by an LD shortcircuit control circuit 11. In a case where a failure of the LD is detected by the detection circuit 13, the LD shortcircuit control unit 11 determines the position of the failed LD to bypass electric current having flowed through the failed LD. Then, the control circuit 11 sends a signal to a predetermined control circuit 14 to thereby operate a predetermined bypass circuit 15. The LD shortcircuit control unit 11 determines the position of the LD, which is to be turned off, according to the position of the failed LD to improve a pointing deviation in the solid-state medium 7. Then, the control unit 11 sends a signal to the control circuit 14 to turn off this LD. Thus, the control unit 11 causes a predetermined bypass circuit 15 to operate thereby to turn off the predetermined LD.
