Optically pumped semiconductor lasers

Jerome V. Moloney, Alexandre Laurain

Research output: Chapter in Book/Report/Conference proceedingChapter


Optically pumped semiconductor disk lasers (OPSL) represent an important emerging technology area offering wavelength versatile, high brightness, high power single mode TEM00 beams, ideal for imaging or coupling into fiber amplifiers. They can provide multi-watt extremely low noise sub-megahertz line width stable outputs or multi-gigahertz repetition rate mode-locked femtosecond pulses with peak powers exceeding multiple kilowatts. Their applications potential is further extended via intra-cavity second and fourth harmonic generation extending source wavelengths into the UV and intra-cavity difference frequency generation yielding widely tunable terahertz and mid-infrared (IR) sources. This article provides a brief overview of key applications and demonstrations of this versatile laser source and the unique microscopic physics principles that are facilitating rapid new developments.
