WebLasers operate on two general principles: light amplification using a gain medium (e.g. Ti:sapphire crystal) and feedback ensured by a cavity (e.g. two mirrors). As light is amplified in the excited gain medium, an intense laser beam is produced due to the feedback of the cavity, which is partially transmitting ( Figure 1 ). Although optical devices also used for continuous light, like beam expanders and spatial filters, may be used for ultrashort pulses, several optical devices have been specifically designed for ultrashort pulses. One of them is the pulse compressor, a device that can be used to control the spectral phase of ultrashort pulses. It is composed of a sequence of prisms, or gratings. When properly adjusted it can alter the spectral phase φ(ω) of the input pulse so that the output pulse …
