In useful phrases, the Yb:KYW crystal has discovered its niche in higher-energy laser apps as a consequence of its power to make substantial Power ultrashort laser pulses while retaining a compact dimension. The interplay of its capabilities �?seamless ytterbium substitution, robust absorption characteristics, ultrashort pulse generation and effectiveness in Electrical power conversion �?positions the Yb:KYW crystal being a cornerstone within the laser technology, masking diverse fields starting from scientific research to industrial apps.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared to its counterpart Yb:KGW, is really a amazing product that performs an important part in laser technology. Its Major function is to crank out ultrashort pulses of light, spanning just a few hundred femtoseconds.
time. Crystals of your compound melts congruently at 1007 oC, nonetheless soften crystallization of top quality crystal is unattainable resulting from phase transition at ~920 oC. The best seeded Resolution process from
Shade-coded reflectivity of a Bragg mirror being a operate of wavelength and angle of your incident beam.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW due to the equivalent dimensions of such chemical components up to one hundred% of Yb-doping may be accomplished. This unique attribute permits ytterbium to take the put of yttrium with almost no disruption towards the crystal’s lattice.
Right before the development of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser obtain medium. It had been in fact used in the main continuously operating crystal laser.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and are employed as lasing components to make ultrashort (~ one hundred-two hundred fs) substantial electric power pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes running at 981 nm supports compact laser techniques.
five mm aside from the middle in the beam caustic. In order to Check out the mode matching simulation, we carried out the experiment with Ng-Slash crystal oscillator, which was designed Beforehand and in a similar situation with simulation [eleven]. As revealed in Figure 3(b) with pink dots and line, the CW output energy is extremely depending on the posture of laser crystal and also the experimental result coincides very well with simulation outcome. As a Notice, multimode Procedure happened in experiment once the dimensions of your pump check here beam is greater than TEM00 cavity method and it results in greater CW output electricity during the displacement location below 3.5 mm.
... at half-peak were produced in a very master oscillator with selfsynchronization on the axial modes, explained in our previously posting. 21 The new version on the laser, unlike that described within our before article, utilised an Yb:KYW crystal having an N pcut (optical axis N p from the index ellipsoid was parallel on the propagation course of the laser radiation), With all the polarization with the created radiation directed along the N m axis.
Superior-power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical applications
When ytterbium-doped laser get media typically show a small quantum defect, ytterbium-doped tungstates allow for for specially modest values. One example is, a 1030-nm Yb:YAG laser would Ordinarily be pumped all around 940 nm, whereas Yb:KGW or Yb:KYW may very well be most proficiently pumped all-around 981 nm.
Li2WO4-WO3 flux was correctly used lowering the growth temperature down below 900 oC. In accordance with one crystal x-ray measurements, the crystal corresponds into the P2/n House group.
