In useful phrases, the Yb:KYW crystal has identified its niche in high-ability laser apps on account of its capability to deliver significant Vitality ultrashort laser pulses although keeping a compact measurement. The interplay of its features �?seamless ytterbium substitution, solid absorption features, ultrashort pulse generation and performance in Strength conversion �?positions the Yb:KYW crystal as being a cornerstone during the laser know-how, covering numerous fields ranging from scientific exploration to industrial applications.
This special characteristic of ultrafast pulses enables nonlinear optical interaction with tissue at small In general publicity, and drives applications like deep-tissue multiphoton microscopy and large-precision eye operation
The Yb:KYW crystal’s proficiency in light-weight absorption at all-around 981 nm will make the crystal well matched for diode pumping. It is actually even further Improved by its exceptional efficiency in this method, coupled with its minimal quantum defect.

Optical layout of the laser with immediate pumping While using the radiation of semiconductor injection lasers. LD is an IPG Photonics laser diode with fiber output with the radiation, WP is often a 50 percent-wave plate, CL is actually a collimating lens, FL is actually a concentrating lens, AE can be an Lively component made from an Yb:KYW crystal, DM is usually a spherical dichroic mirror, M1-M6 are the cavity mirrors, OC may be the output mirror, and SAM is often a semiconductor saturable-absorber mirror.
Adhesion Take a look at Compliant with MIL-C-675C military services standards, an adhesion exam included making use of a tape that fulfills LT-90 specifications on to the lens film layer. The tape was affixed absolutely and then taken out vertically. This procedure was carried out 3 times, resulting in no blistering or peeling.
Raman, luminescence and transmission spectra expose optical attributes owing on the presence of thulium ions, and for that reason the supplies could possibly be additional analyzed within the scope of laser and luminescence applications.
five mm apart from the middle in the beam caustic. So that you can check the method matching simulation, we performed the experiment with Ng-Minimize crystal oscillator, which was created Earlier As well as in a very same issue with simulation [eleven]. As proven in Determine three(b) with red dots and line, the CW output electric power is very dependent on the situation of laser crystal as well as experimental outcome coincides nicely with simulation outcome. As being a note, multimode Procedure occurred in experiment once the measurement of your pump beam is bigger than get more info TEM00 cavity mode and it causes larger CW output power during the displacement region beneath 3.5 mm.
For tungstates, the ytterbium doping focus can be very high without the need of important quenching because the changed ions have an incredibly comparable ion radius, along with the inter-ion distance is pretty huge.
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW mainly because of the identical measurements of those chemical components up to a hundred% of Yb-doping may be attained.
While ytterbium-doped laser get media typically show a little quantum defect, ytterbium-doped tungstates enable for especially modest values. By way of example, a 1030-nm Yb:YAG laser would Typically be pumped about 940 nm, whereas Yb:KGW or Yb:KYW could possibly be most competently pumped close to 981 nm.
