In practical terms, the Yb:KYW crystal has identified its niche in high-power laser programs as a result of its capacity to create higher Electrical power ultrashort laser pulses when maintaining a compact sizing. The interplay of its characteristics �?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, covering numerous fields ranging from scientific analysis to industrial apps.
This exclusive attribute of ultrafast pulses enables nonlinear optical conversation with tissue at lower In general publicity, and drives apps for example deep-tissue multiphoton microscopy and significant-precision eye surgery
We current a dual-crystal Yb:KGW laserthat iscapable to function as being a Q-switched oscillator with output energy as much as 24 W and pulse duration of 20 ns,or as a regenerative amplifier with output electric power approximately 21 W and pulse duration underneath 200 fs immediately after compression of chirped pulses. Each lasers have great beam high-quality with beam parameter M2
Color-coded reflectivity of the Bragg mirror as a function of wavelength and angle of your incident beam.
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW because of the related sizes of such chemical features around 100% of Yb-doping could be realized. This exclusive characteristic permits ytterbium to go ahead and take location of yttrium with pretty much no disruption to your crystal’s lattice.
After air drying and subsequent cleaning by using a cotton cloth soaked in Liquor, the film surface showed no indications of peeling or scratches.
Raman, luminescence and transmission spectra expose optical capabilities owing on the presence of thulium ions, and as a consequence the components could be even further researched during the scope of laser and luminescence programs.
5 mm besides the center of your beam caustic. To be able to check the method matching simulation, we executed the experiment with Ng-cut crystal oscillator, which was produced Formerly As well as in a same problem with simulation [eleven]. As proven in Determine three(b) with pink dots and line, the CW output energy is extremely dependent on the situation of laser crystal as well as experimental outcome coincides effectively with simulation end result. As being a Observe, multimode operation transpired in experiment if the dimensions of your pump beam is more substantial than TEM00 cavity mode and it causes larger CW output electric power within the displacement location down below 3.5 mm.

This tandem of characteristics has much-reaching implications, notably in the development of compact but powerfull lasers.
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared with its counterpart Yb:KGW, is often a impressive content that performs a very important purpose in laser technology. Its Main functionality should be to generate ultrashort pulses of sunshine, spanning just a few hundred femtoseconds.
