The achieve bandwidth e.g. of Yb:KGW and Yb:KYW may be very huge when compared with that of Yb:YAG. This allows for extensive wavelength tunability and for A great deal shorter pulse durations from mode-locked lasers. Values nicely under one hundred fs are obtained with passive manner locking.

We existing a dual-crystal Yb:KGW laserthat iscapable to operate like a Q-switched oscillator with output electricity as many as 24 W and pulse size of 20 ns,or like a regenerative amplifier with output electricity around 21 W and pulse duration below two hundred fs immediately after compression of chirped pulses. Both equally lasers have exceptional beam good quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Display screen powerful peaks at 980 nm and 1030 nm, respectively, ensuring efficient Power conversion and large functionality in laser programs.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW mainly because of the similar dimensions of such chemical factors approximately 100% of Yb-doping could be obtained. This special attribute permits ytterbium to take the area of yttrium with virtually no disruption to your crystal’s lattice.
Adhesion Exam Compliant with MIL-C-675C military standards, an adhesion exam associated making use of a tape that fulfills LT-90 technical specs on to the lens film layer. The tape was affixed absolutely after which you can taken off vertically. This treatment was performed thrice, resulting in no blistering or peeling.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and they are employed as lasing supplies to deliver ultrashort (~ 100-two hundred fs) high electricity pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser devices.
five mm other than the middle from the beam caustic. In order to Test the mode matching simulation, we done the experiment with Ng-Reduce crystal oscillator, which was formulated previously and in a exact problem with simulation [eleven]. As revealed in Figure 3(b) with pink dots and line, the CW output electrical power is very depending on the place of laser crystal along with the experimental final result coincides properly with simulation final result. As being a Notice, multimode Procedure transpired in experiment if the sizing of the pump beam is bigger than TEM00 cavity mode and it leads to larger CW output electricity while in the displacement area down below three.5 mm.

Simultaneously, a shorter laser wavelength could be attained; it is achievable to operate which has a quantum defect properly beneath 1%. To be a consequence, the heat technology is usually so tiny that this partly compensates the decreased thermal conductivity.
