In simple conditions, the Yb:KYW crystal has uncovered its specialized niche in high-power laser applications due to its ability to deliver superior Vitality ultrashort laser pulses whilst sustaining a compact sizing. The interaction of its functions �?seamless ytterbium substitution, powerful absorption characteristics, ultrashort pulse era and efficiency in Electrical power conversion �?positions the Yb:KYW crystal being a cornerstone within the laser technology, masking various fields starting from scientific research to industrial apps.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, as compared to its counterpart Yb:KGW, is really a outstanding content that plays a significant purpose in laser technology. Its primary function is to generate ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
We existing a dual-crystal Yb:KGW laserthat iscapable to function as a Q-switched oscillator with output power approximately 24 W and pulse size of 20 ns,or like a regenerative amplifier with output electricity approximately 21 W and pulse length beneath 200 fs following compression of chirped pulses. Each lasers have fantastic beam top quality with beam parameter M2
Color-coded reflectivity of a Bragg mirror like a purpose of wavelength and angle of your incident beam.
Optical structure of a laser with immediate pumping Together with the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output from the radiation, WP is actually a fifty percent-wave plate, CL can be a collimating lens, FL can be a focusing lens, AE is really an active ingredient created from an Yb:KYW crystal, DM is often a spherical dichroic mirror, M1-M6 are classified as the cavity mirrors, OC is definitely the output mirror, and SAM is really a semiconductor saturable-absorber mirror.
Adhesion Check Compliant with MIL-C-675C navy benchmarks, an adhesion test involved applying a tape that meets LT-90 specs onto the lens film layer. The tape was affixed totally after which taken out vertically. This treatment was executed thrice, leading to no blistering or peeling.
FIG. 1. Optical structure of a laser with immediate pumping Together with the radiation of semiconductor injection lasers. LD is definitely an IPG Photonics laser diode with fiber output
five mm besides the center in the beam caustic. In an effort to Check out the mode matching simulation, we executed the experiment with Ng-Slice crystal oscillator, which was designed Formerly As well as in a similar problem with simulation [eleven]. As demonstrated in Figure three(b) with red dots and line, the CW output electric power is highly dependent on the situation of laser crystal as well as the experimental final result coincides perfectly with simulation end result. As a Take note, multimode operation transpired in experiment in the event the dimension with the pump beam is bigger than TEM00 cavity method and it results in larger CW output electric power in the displacement area down below three.five mm.

... Not only the posture click here of crystal during the cavity but will also the amplification axis of crystal has an effect on the laser operation tremendously, because the absorption and emission cross sections of your crystal are rather unique based on the orientation from the crystal.

The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at area temperature were being measured. The emission spectrum and lifetime on the three File four excited state had been decided. Applying standard and modified Judd–Ofelt theories, the intensity parameters and also the radiative lifetimes have been calculated and very good arrangement Along with the experimental effects was received for both equally theories.
Ask RP Photonics for almost any suggestions about tungstate lasers, like femtosecond lasers and higher-ability lasers.
