In practical terms, the Yb:KYW crystal has discovered its market in superior-power laser applications on account of its power to produce significant Power ultrashort laser pulses when sustaining a compact dimensions. The interaction of its options �?seamless ytterbium substitution, sturdy absorption traits, ultrashort pulse technology and effectiveness in Electrical power conversion �?positions the Yb:KYW crystal for a cornerstone from the laser technologies, covering diverse fields starting from scientific study to industrial apps.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, as compared to its counterpart Yb:KGW, is usually a impressive materials that performs a very important job in laser technology. Its Major operate is usually to crank out ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
We present a dual-crystal Yb:KGW laserthat iscapable to work to be a Q-switched oscillator with output power as much as 24 W and pulse length of twenty ns,or like a regenerative amplifier with output electrical power around 21 W and pulse length beneath 200 fs right after compression of chirped pulses. The two lasers have exceptional beam good quality with beam parameter M2
Coloration-coded reflectivity of a Bragg mirror to be a function of wavelength and angle from the incident beam.
This paper describes a femtosecond laser regenerative amplifier according to two Yb:KYW crystals with immediate longitudinal pumping by effective linear arrays of semiconductor injection lasers possessing fiber output. To stop spectral narrowing in the course of amplification and also the corresponding lengthening of the amplified pulse when it is actually compressed, a mix of two Yb:KYW crystals were applied, Along with the spectral maxima in the amplification shifted relative to one another and with spectral profiling from the amplified radiation.
Adhesion Test Compliant with MIL-C-675C armed forces benchmarks, an adhesion test included implementing a tape that satisfies LT-ninety requirements on to the lens movie layer. The tape was affixed fully and after that eliminated vertically. This method was carried out three times, causing no blistering or peeling.
Raman, luminescence and transmission spectra expose optical options owing to your presence of thulium ions, get more info and thus the materials could be further more researched in the scope of laser and luminescence apps.
A higher brightnessQ-switched oscillator and regenerative amplifier according to a twin-crystal Yb:KGW laser

By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW a result of the equivalent sizes of such chemical factors as much as a hundred% of Yb-doping may be accomplished.
When ytterbium-doped laser attain media usually exhibit a small quantum defect, ytterbium-doped tungstates permit for specifically little values. By way of example, a 1030-nm Yb:YAG laser would Commonly be pumped all over 940 nm, While Yb:KGW or Yb:KYW may be most effectively pumped about 981 nm.
