Threshold detector with hysteresis — The threshold detector with hysteresis, very similar to the zero crossing threshold detector, is an electronic circuit consisting of an operational amplifier and a series of resistors that provide hysteresis. Like other detectors, this device… … Wikipedia
Lasing threshold — The lasing threshold is the lowest excitation level at which a laser s output is dominated by stimulated emission rather than by spontaneous emission. Below the threshold, the laser s output power rises slowly with increasing excitation. Above… … Wikipedia
