Heat generation during the operation of lasers and amplifiers negatively affects a wide range of performance and packaging considerations. Accordingly, the thermal management of such systems remains of critical importance. This paper reviews the sources of heat in active fiber lasers and amplifiers, and describes recent successes using all-optical means to reduce heat generation, including anti-Stokes fluorescence cooling, radiation balancing, and dual-wavelength pumping.
