Blue-Green Lasers and Electrodeless Flashlamps
Abstract
This paper addresses the questions of combining the technology of moderate pressure electrodeless discharge lamps with the efficiency of a resonantly pumped solid state laser to achieve an efficient, compact, and reliable blue green laser. The scheme is based on resonant absorption of the 1D2 state of Pr(+3) which coincides with strong yellow lines of a sodium discharge at 589 nm. A Q switched lasing transition to the 3F3 state can be doubled into the desired blue green region. Estimates show that a moderate pressure electrodeless flashlamp should emit roughly 30% of its light in the 589 nm band. More generally, the moderate pressure electrodeless flashlamp should be an effective and efficient emitter of resonant radiation throughout the visible and UV region, opening possibilities for other resonantly pumped lasers. Several specific possibilities are pointed out, including an energy efficient system at 610 nm, and a candidate inertial fusion driven at 250 nm.
