Cavity blackbody-pumpd lasers: Present research status

The basic concept for a blackbody cavity is given. A comparison between the direct solar-pumped laser efficiency and one which is indirectly pumped by a blackbody cavity shows that they are similar to a carnot cycle. The blackbody spectrum used to optically pump the lasant material is shown. Also shown is the physical principle behind the blackbody laser idea. An example of an infrared laser media is given. A system study was conducted to scale cavity blackbody pumped lasers to high output powers.
