    However, due to the cost and potential dangers, this is an uncommon hobby. Some hobbyists salvage laser diodes from broken DVD players (red), Blu-ray players (violet), or even higher power laser diodes from CD or DVD burners. [129] Hobbyists have also used surplus lasers taken from retired military applications and modified them for holography ...

    Photomicrographs of a DBR laser. A distributed Bragg reflector laser (DBR) is a type of single frequency laser diode. Other practical types of single frequency laser diodes include DFB lasers and external cavity diode lasers. A fourth type, the cleaved-coupled-cavity laser has not proven to be commercially viable.

    IPG invested much of its remaining capital in the development of: (1) high-power industrial fiber lasers; (2) mass production lines; and (3) semiconductor pump laser diode technology. IPG pursued raising the maximum wattage of fiber laser technology. [23] Between 2002 and 2003, IPG developed multi-kW industrial class fiber lasers.

    Couillaud, in collaboration with Nobel Prize Laureate Theodor W. Hänsch, developed the Hansch-Couillaud technique for laser frequency stabilization, [18] and was instrumental in the development of dye, diode-pumped solid-state lasers, and Ti-sapphire lasers in his roles at Coherent. The Couillaud Prize is awarded to early-career professionals ...
