WebPulsed operation of lasers refers to any laser not classified as continuous wave, so that the optical power appears in pulses of some duration at some repetition rate. [1] This encompasses a wide range of technologies addressing a number of different motivations. Some lasers are pulsed simply because they cannot be run in continuous mode.

WebA pulsed laser is a system which will emit light in the form of optical pulses, rather than a continuous wave (CW). There are numerous methods to achieve laser pulsing, but the end result follows the same principles. A pulsed laser periodically emits pulses of energy in an ultra-short time duration. WebIn this application, the optocoupler is used to detect the operation of the switch or another type of digital input signal. This is useful if the switch or signal being detected is within an electrically noisy environment. The output can be used to operate an external circuit, light or as an input to a PC or microprocessor.
