Sub 10-fs Pulses with Chirped Laser Mirrors

The development of broadband saturable semiconductor absorber mirrors and of dispersion-engineered chirped multilayer dielectric mirrors has allowed the realization of self-starting ultrashort laser pulses, which routinely reach sub-10 fs pulsewidths and peak powers above the megawatt level. [Pg.299]

Double-chirped mirror Bragg wavelength and coupling chirped [Pg.300]

Instead of varying the thicknesses of the layers, one can also produce chirped mirrors by smoothly altering the indices of refraction and the difference between them (nr - i) (Fig. 6.33). [Pg.300]

These mirrors may be regarded as one-dimensional holograms that are generated when a chirped and an unchirped laser pulse from opposite directions are superimposed in a medium where they generate a refractive index pattern proportional to their total intensity [693]. When a chirped pulse is reflected by such a hologram, it becomes compressed, similar to the situation with phase-conjugated mirrors. [Pg.300]

Bottom reflector (AlAs/AIGaAs Bragg mirror) [Pg.637]

A combination of saturable semiconductor media in front of a chirped mirror and KLM techniques can be used for reliable operation of sub-10-fs pulses. In Fig. 11.30 such a multilayer saturable absorber is illustrated. [Pg.638]
