Er: YLF Laser Development

This results of the first six months of a fourteen month program entitled Er(3+): YLF Solid State Laser Development are reported. The program goals are: Growth of 0.25 inch diameter by 3-inch length laser rods with scattering less than 0.5% cm-1; Q-switched operation at a PRF of 10 Hz with an output...

Zusammenfassung:	This results of the first six months of a fourteen month program entitled Er(3+): YLF Solid State Laser Development are reported. The program goals are: Growth of 0.25 inch diameter by 3-inch length laser rods with scattering less than 0.5% cm-1; Q-switched operation at a PRF of 10 Hz with an output power in excess of 1 watt; beam divergence less than 5 milliradians at full angel, 90% energy points; and operation at an overall efficiency of 0.5% in the Q-switched mode.
