In practical terms, the Yb:KYW crystal has identified its market in substantial-electric power laser apps as a consequence of its power to crank out significant Strength ultrashort laser pulses although preserving a compact size. The interaction of its characteristics �?seamless ytterbium substitution, sturdy absorption traits, ultrashort pulse era and performance in Strength conversion �?positions the Yb:KYW crystal as a cornerstone during the laser technological know-how, masking various fields starting from scientific research to industrial programs.
This is the preview of membership content material, log in through an establishment to examine entry. Entry this information
The Yb:KYW crystal’s proficiency in light-weight absorption at around 981 nm tends to make the crystal well suited for diode pumping. It's additional enhanced by its remarkable performance in this process, coupled with its reduced quantum defect.
The absorption and emission spectra of Yb:KYW Crystals Screen solid peaks at 980 nm and 1030 nm, respectively, making sure efficient Power conversion and substantial effectiveness in laser devices.
Ultrafast lasers, with pulse widths of some picoseconds (ten−12 s) or considerably less, permit time resolution needed in laser-thrilled fluorescence lifetime spectroscopy and imaging approaches.Additionally, they provide higher pulse peak powers at high repetition fees and average regular output powers.
Just before the event of Nd:YAG, Nd3+:CaWO4 was a vital uncommon-earth-doped laser get medium. It was in reality Utilized in the initial consistently operating crystal laser.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and they are made use of as lasing products to make ultrashort (~ 100-two hundred fs) substantial electrical power pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser systems.
five mm apart from the middle of the beam caustic. So as to Examine the method matching simulation, we done the experiment with Ng-Slice crystal oscillator, which was created Earlier and in a similar issue with simulation [eleven]. As shown in Figure three(b) with crimson dots and line, the CW output electric power is extremely dependent on the situation of laser crystal along with the experimental end result coincides very well with simulation outcome. As a Observe, multimode operation occurred in experiment if the size with the pump beam is larger sized than TEM00 cavity mode and it brings about higher CW output electricity within the displacement region underneath three.five mm.
