Q Switching - SPIE - the international society for optics and photonics
www.spie.orgIn a first phase, the gain medium is pumped, while the extraction of energy as laser light is prevented by keeping the resonator losses high (that is, the Q factor is kept low). This can be done with active or passive means. The resonator losses are then
