Claim:
1. A method comprising: activating a laser pump module comprising: selectively enabling, with the controller, a first current to the first diode subset; outputting, from the laser pump module, a first pump energy with a first operating wavelength and a first power level of 10-50 W; selectively enabling, with the controller, a second current to the second diode subset; outputting less than one second after the first pump energy, from the laser pump module, a second pump energy with a second operating wavelength at a second power level; and adjusting, with the controller and the temperature control system, (i) a magnitude of the first or second current and (ii) an operating temperature of the plurality of laser diodes to maintain the first and second operating wavelengths within the operating wavelength range of the gain medium, wherein the first pump energy is different that the second pump energy, there is at least 50 W separating the first and second power levels, and the operating wavelength range of the gain medium includes the first and second operating wavelengths.
