Radiation Balanced Laser
A typical problem with high-power lasers is the heat generated in laser operation, which can make lots of problems in laser operation, including thermal mode instability, thermal lensing so thermal heat mitigation in laser gain medium is very crucial. One of the approach to diminish the heat generated in the laser gain medium is the concept of radiation balanced lasers or athermal lasers, invented by Steven R. Bowman, at the Naval Research Laboratory in  Washington, DC. The idea is to remove the heat generated by the laser operation with the optical refrigeration that leads to eliminate heat load. In certain condition, the fluorescence or radiative cooling can totally compensate heating associated with laser operation.
