In simple conditions, the Yb:KYW crystal has found its market in large-energy laser purposes resulting from its capacity to create higher Electrical power ultrashort laser pulses even though protecting a compact dimension. The interaction of its options �?seamless ytterbium substitution, potent absorption characteristics, ultrashort pulse technology and efficiency in Electricity conversion �?positions the Yb:KYW crystal being a cornerstone inside the laser technologies, masking various fields starting from scientific research to industrial apps.
That is a preview of membership material, log in by using an institution to examine access. Entry this short article
time. Crystals with the compound melts congruently at 1007 oC, even so melt crystallization of top of the range crystal is extremely hard on account of phase changeover at ~920 oC. The very best seeded solution system from
The absorption and emission spectra of Yb:KYW Crystals Show robust peaks at 980 nm and 1030 nm, respectively, making certain productive Electricity conversion and superior performance in laser methods.
Ultrafast lasers, with pulse widths of a few picoseconds (10−twelve s) or a lot less, allow the time resolution required in laser-excited fluorescence life span spectroscopy and imaging tactics.Additionally, they provide high pulse peak powers at superior repetition costs and moderate ordinary output powers.
In advance of the development of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser obtain medium. It had been in fact used in the primary consistently operating crystal laser.
FIG. 1. Optical format of the laser with direct pumping with the radiation of semiconductor injection lasers. LD is definitely an IPG Photonics laser diode with fiber output
5 mm aside from the center of the beam caustic. In order to Look at the method matching simulation, we carried out the experiment with Ng-cut crystal oscillator, which was made Earlier and in a exact affliction with simulation [11]. As demonstrated in Figure three(b) with red dots and line, the CW output electric power is highly depending on the place of laser crystal as well as the experimental result coincides very well with simulation outcome. For a Be aware, multimode Procedure happened in experiment when the measurement of your pump beam is greater than TEM00 cavity method and it causes larger CW output electric power in the displacement region beneath 3.5 mm.
EKSMA Optics utilizes cookies to give you the finest searching knowledge. For those who go on to utilize our solutions, We more info are going to presume that you choose to comply with using this sort of cookies.
By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW a result of the equivalent sizes of such chemical aspects as much as a hundred% of Yb-doping could possibly be accomplished.
Though ytterbium-doped laser gain media typically exhibit a small quantum defect, ytterbium-doped tungstates permit for specifically modest values. By way of example, a 1030-nm Yb:YAG laser would Generally be pumped all around 940 nm, While Yb:KGW or Yb:KYW might be most effectively pumped around 981 nm.
This tandem of characteristics has much-reaching implications, significantly in the construction of compact nevertheless powerfull lasers.
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 in the three File four energized point out were determined. Working with standard and modified Judd–Ofelt theories, the depth parameters and also the radiative lifetimes had been calculated and excellent arrangement With all the experimental benefits was acquired for the two theories.
Check with RP Photonics for almost any guidance concerning tungstate lasers, like femtosecond lasers and significant-power lasers.
