We current a twin-crystal Yb:KGW laserthat iscapable to function being a Q-switched oscillator with output ability as much as 24 W and pulse length of twenty ns,or to be a regenerative amplifier with output power up to 21 W and pulse period down below two hundred fs just after compression of chirped pulses. Both of those lasers have fantastic beam excellent with beam parameter M2

This paper describes a femtosecond laser regenerative amplifier based upon two Yb:KYW crystals with immediate longitudinal pumping by strong linear arrays of semiconductor injection lasers possessing fiber output. To stop spectral narrowing in the course of amplification and also the corresponding lengthening of the amplified pulse when it is actually compressed, a mix of two Yb:KYW crystals had been made use of, Along with the spectral maxima in the amplification shifted relative to one another and with spectral profiling of the amplified radiation.
The monoclinic crystal structures ends in a all-natural birefringence, helping to stay clear of thermally induced polarization rotation and depolarization decline.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and so are employed as lasing resources to deliver ultrashort (~ a hundred-two hundred fs) higher ability pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes running at 981 nm supports compact laser devices.
5 mm apart from the middle from the beam caustic. In order to Test the mode matching simulation, we done the experiment with Ng-Slice crystal oscillator, which was produced Beforehand and in a very same condition with simulation [11]. As revealed in Figure 3(b) with pink dots and line, the CW output energy is extremely depending on the position of laser crystal along with the experimental final result coincides nicely with simulation end result. To be a note, multimode operation transpired in experiment if the dimensions in the pump beam is much larger than TEM00 cavity method and it will cause bigger CW output power in the displacement region below three.five mm.

... Not just the position of crystal during the cavity but in addition click here the amplification axis of crystal has an effect on the laser operation considerably, because the absorption and emission cross sections of the crystal are pretty unique based on the orientation of the crystal.
The thermal conductivity of widespread double tungstates is of the purchase to three–four W/(K m) �?which is not undesirable in contrast with other laser crystals (While numerous periods less than for YAG), and relatively substantial as opposed Using the thermal conductivity of standard glasses.

Concurrently, a shorter laser wavelength could be attained; it is feasible to work having a quantum defect perfectly down below one%. For a consequence, the warmth generation may be so modest that this partly compensates the lower thermal conductivity.
