In practical terms, the Yb:KYW crystal has found its niche in high-energy laser applications due to its power to deliver significant Electrical power ultrashort laser pulses when protecting a compact dimension. The interplay of its characteristics �?seamless ytterbium substitution, solid absorption traits, ultrashort pulse technology and effectiveness in Power conversion �?positions the Yb:KYW crystal to be a cornerstone while in the laser engineering, covering diverse fields starting from scientific research to industrial programs.
The comparison with Eyeglasses is suitable Because the big gain bandwidth will allow e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
The Yb:KYW crystal’s proficiency in gentle absorption at all over 981 nm will make the crystal like minded for diode pumping. It truly is further more Increased by its remarkable efficiency in this process, coupled with its reduced quantum defect.

Ultrafast lasers, with pulse widths of a few picoseconds (10−twelve s) or fewer, empower the time resolution needed in laser-enthusiastic fluorescence life time spectroscopy and imaging strategies.Additionally, they produce higher pulse peak powers at significant repetition prices and reasonable average output powers.
Right after air drying and subsequent cleansing having a cotton fabric soaked in alcohol, the film floor showed no signs of peeling or scratches.
FIG. 1. Optical structure of a laser with immediate pumping Along with the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output
five mm in addition to the middle in the beam caustic. As a way to Verify the manner matching simulation, we done the experiment with Ng-Lower crystal oscillator, which was created Beforehand and in a identical problem with simulation [eleven]. As proven in Determine 3(b) with pink dots and line, the CW output electrical power is very dependent on the placement of laser crystal and also the experimental result coincides very well with simulation outcome. To be a Notice, multimode Procedure occurred in experiment if the size with the pump beam is larger than TEM00 cavity mode and it will cause greater CW output electricity while in the displacement location down below three.five mm.

By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW due to equivalent dimensions of such chemical components as many as a hundred% of Yb-doping may be attained.
