Abstract:

During the past three years we have made substantial progress toward the goal of a fiber coupled, diode laser pumped 1OOW cw NdYAG minislab laser. We have diode pumped a 1W ring cavity laser and have operated it in a single frequency. We have diode pumped a testbed minislab NdYAG laser using fiber coupled diode laser bars and generated 5W of cw, TEMoo mode output power. We have designed and are implementing a 5OW cw minislab NdYAG laser to be pumped by 25 diode laser bars coupled through optical fibers. We plan, in the second phase of this program, to achieve the 1OOW cw output power level in a minislab NdYAG laser approach proposed as the goal of this research program In addition, we have demonstrated single frequency control of a high power NdYAG laser oscillator by injection locking have frequency stabilized NdYAG oscillators by locking to high finesse Fabry Perot resonators have absolutely stabilized NdYAG to one part in 10 to the -13th power by locking to iodine have frequency converted NdYAG by second harmonic generation to 11.2W of cw TEMoo mode green output have demonstrated the first cw 2 microns OPO in lithium niobate and have demonstrated the first cw singly resonant OPO with 2W of output in a single frequency in KTP.
