In sensible phrases, the Yb:KYW crystal has uncovered its niche in superior-power laser programs resulting from its ability to deliver higher Strength ultrashort laser pulses while maintaining a compact dimension. The interplay of its characteristics �?seamless ytterbium substitution, potent absorption traits, ultrashort pulse technology and performance in Electrical power conversion �?positions the Yb:KYW crystal being a cornerstone within the laser engineering, masking various fields starting from scientific investigation to industrial programs.

We present a dual-crystal Yb:KGW laserthat iscapable to operate being a Q-switched oscillator with output ability up to 24 W and pulse size of 20 ns,or as being a regenerative amplifier with output electrical power approximately 21 W and pulse duration down below 200 fs following compression of chirped pulses. Both lasers have fantastic beam high quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Screen strong peaks at 980 nm and 1030 nm, respectively, ensuring effective Power conversion and higher efficiency in laser programs.
By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW due to the equivalent sizes of such chemical components as much as one hundred% of Yb-doping could be attained. This exceptional attribute permits ytterbium to take the location of yttrium with nearly no disruption to your crystal’s lattice.
Adhesion Examination Compliant with MIL-C-675C navy specifications, an adhesion take a look at involved applying a tape that satisfies LT-90 technical specs onto the lens film layer. The tape was affixed totally and after that taken out vertically. This procedure was done 3 times, causing no blistering or peeling.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and so are applied as lasing supplies to crank out ultrashort (~ one hundred-200 fs) superior electricity pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser methods.
5 mm apart from the middle of your beam caustic. So as to Test the mode matching simulation, we executed the experiment with Ng-Slice crystal oscillator, which was developed Formerly As well as in a same affliction with simulation [11]. As shown in Determine three(b) with red dots and line, the CW output power is extremely dependent on the placement of laser crystal plus the experimental consequence coincides effectively with simulation end result. For a Notice, multimode Procedure transpired in experiment in the event the dimensions of the pump beam is larger than TEM00 cavity method and it will cause greater CW output electric power from the displacement region underneath 3.five mm.
... at half-height ended up generated within a grasp oscillator with selfsynchronization of the axial modes, described within our before write-up. 21 The new version on the laser, as opposed to that explained in our before write-up, made use of an Yb:KYW crystal by having an N pcut (optical axis N p with the index ellipsoid was parallel for the propagation path on the laser radiation), Using the polarization on the created radiation directed together the N m axis.

While ytterbium-doped laser get media normally show a small quantum defect, ytterbium-doped tungstates allow for for notably small values. One example is, a 1030-nm Yb:YAG laser would Usually be pumped all over 940 nm, Whilst Yb:KGW or Yb:KYW could possibly be most competently pumped about 981 nm.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, is often a remarkable materials that plays a significant function in laser technology. Its primary function is usually to deliver ultrashort pulses of light, spanning only a few hundred femtoseconds.
