We existing a twin-crystal Yb:KGW laserthat iscapable to work being a Q-switched oscillator with output electrical power as many as 24 W and pulse duration of 20 ns,or being a regenerative amplifier with output electricity approximately 21 W and pulse length beneath 200 fs after compression of chirped pulses. Both lasers have excellent beam high-quality with beam parameter M2

By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW as a result of related measurements of those chemical things up to 100% of Yb-doping might be attained. This special characteristic permits ytterbium to take the location of yttrium with practically no disruption for the crystal’s lattice.
The monoclinic crystal constructions leads to a natural birefringence, assisting to prevent thermally induced polarization rotation and depolarization reduction.
Raman, luminescence and transmission spectra expose optical characteristics owing to your existence of thulium ions, and as a consequence the elements can be further studied in the scope of laser and luminescence applications.
five mm other than the center of the beam caustic. In order to Look at the method matching simulation, we carried out the experiment with Ng-Reduce crystal oscillator, which was developed Beforehand As well as in a very same problem with simulation [eleven]. As proven in Determine 3(b) with purple dots and line, the CW output electrical power is very dependent on the posture of laser crystal as well as the experimental result coincides nicely with simulation consequence. As being a Observe, multimode operation transpired in experiment if the dimensions in the pump beam is more substantial than TEM00 cavity mode and it causes larger CW output electric power within the displacement location below three.five mm.

Substantial-ability repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical purposes
The thermal conductivity of widespread double tungstates is of your purchase to 3–four W/(K m) �?which isn't terrible in contrast with other laser crystals (although numerous periods less than for YAG), and relatively substantial as opposed Using the thermal conductivity of standard glasses.
This tandem of attributes has significantly-achieving implications, specifically in the development of compact yet powerfull lasers.
