Not being related to electronic transitions, theRamanshift is relative concerning the irradiating wavelength, and therefore, unless pursuing coherent excitation, laser source tunability is not required. Firefox or Chrome)! By assuming a train of continuously repeated, periodical, square pulses with repetition rate fR, pulse duration tP and average power PAV, the pulse energy EP and peak power PP calculations are trivial, with pulse energy provided by the ratio between average power and repetition rate and peak power provided by the ratio between energy and pulse duration: In actively Q-switched lasers, the user controls the pulsed laser output, so that no laser pulse emission occurs without providing a proper input signal, aka the trigger. In applications such as laser micromachining, one sometimes achieves better quality results with femtosecond pulses, but picosecond pulses are often sufficient when the process is sufficiently optimized overall. While the primary difference between traditional LIDAR and 3D scanning applications is the distance from the laser to the target, both sets of applications benefit from the features provided by high-quality microchip lasers.
