Abstract
A selective emitter pumped rare earth laser provides an additional type of laser for use in many laser applications. Rare earth doped lasers exist which are pumped with flashtubes or laser diodes. The invention uses a rare earth emitter to transform thermal energy input to a spectral band matching the absorption band of a rare earth in the laser in order to produce lasing.
Claims10
A laser comprising:
- a resonant cavity;
- a combustion-heated emitter having a selective energy emission band;
- and
- a rare earth doped laser rod within said resonant cavity having an energy absorption band matching said selective energy emission band, said emitter and rod being arranged to allow photon energy from said emitter to pump said rod.
