Abstract

This paper examines several characteristics and phenomenon associated with the optimization of diode pumped erbium ytterbium glass microlasers. Test results indicate that within an erbium ytterbium glass gain element, the excited erbium (laser) ion effective pump depth is larger than the excited ytterbium (sensitizer) ion effective pump depth. Designed specifically for diode pumping, JD phosphate laser glass host material exhibits high rare earth and sensitizer ion solubility. This enhanced doping capability allows the JD glass to be used in a variety of diode pump architectures that are not possible with most conventional crystal & glass laser materials. Our study has shown that new small gain element composite laser glass architectures & designs may be made used to more efficiently capture, contain and uniformly distribute the diode laser pump light. We expect this work to will lead to the next generation of high peak & average power "eye-safe" diode pumped microlasers for use in rangefinding, imaging, illumination tracking and targeting applications.
