KYW Crystal - An Overview

The obtain bandwidth e.g. of Yb:KGW and Yb:KYW is quite massive when compared with that of Yb:YAG. This permits for wide wavelength tunability and for A lot shorter pulse durations from mode-locked lasers. Values effectively under a hundred fs happen to be obtained with passive method locking.

The comparison with Eyeglasses is appropriate For the reason that huge achieve bandwidth allows e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.

Femtosecond laser determined by Yb:KYW crystals with suppression of spectral narrowing in a very regenerative amplifier by spectral profiling of the pulse

This paper describes a femtosecond laser regenerative amplifier depending on two Yb:KYW crystals with immediate longitudinal pumping by effective linear arrays of semiconductor injection lasers obtaining fiber output. To avoid spectral narrowing in the course of amplification as well as corresponding lengthening of your amplified pulse when it is compressed, a combination of two Yb:KYW crystals ended up used, With all the spectral maxima with the amplification shifted relative to one another and with spectral profiling of your amplified radiation.

Right after air drying and subsequent cleaning by using a cotton fabric soaked in Alcoholic beverages, the movie area showed no indications of peeling or scratches.

five mm other than the center of the beam caustic. As a way to Test the method matching simulation, we performed the experiment with Ng-Reduce crystal oscillator, which was developed previously As well as in a same issue with simulation [eleven]. As shown in Figure 3(b) with crimson dots and line, the CW output electricity is very dependent on the placement of laser crystal and the experimental consequence coincides nicely with simulation end result. Being a note, multimode Procedure happened in experiment once the dimension of the pump beam is greater than TEM00 cavity manner and it causes higher CW output energy in the displacement area below three.5 mm.

For tungstates, the ytterbium doping concentration can be extremely significant devoid of important quenching because the changed ions have an incredibly equivalent ion radius, as well as inter-ion length is relatively substantial.
