In practical conditions, the Yb:KYW crystal has observed its area of interest in large-electricity laser programs because of its capability to generate significant Power ultrashort laser pulses while protecting a compact measurement. The interplay of its options �?seamless ytterbium substitution, solid absorption properties, ultrashort pulse era and performance in Strength conversion �?positions the Yb:KYW crystal to be a cornerstone while in the laser engineering, covering assorted fields starting from scientific research to industrial programs.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, compared to its counterpart Yb:KGW, is really a impressive content that plays a vital position in laser know-how. Its Key operate would be to deliver ultrashort pulses of light, spanning only a few hundred femtoseconds.
We existing a dual-crystal Yb:KGW laserthat iscapable to function as a Q-switched oscillator with output electrical power around 24 W and pulse length of 20 ns,or as a regenerative amplifier with output electric power as much as 21 W and pulse period under 200 fs after compression of chirped pulses. Both of those lasers have excellent beam high-quality with beam parameter M2

This paper describes a femtosecond laser regenerative amplifier dependant on two Yb:KYW crystals with direct longitudinal pumping by impressive linear arrays of semiconductor injection lasers possessing fiber output. To stop spectral narrowing for the duration of amplification and the corresponding lengthening with the amplified pulse when it is actually compressed, a mix of two Yb:KYW crystals had been utilized, Using the spectral maxima on the amplification shifted relative more info to each other and with spectral profiling of the amplified radiation.
Just before the development of Nd:YAG, Nd3+:CaWO4 was a vital rare-earth-doped laser get medium. It absolutely was in truth Utilized in the primary constantly functioning crystal laser.
Raman, luminescence and transmission spectra reveal optical functions owing into the presence of thulium ions, and for that reason the supplies may very well be more examined inside the scope of laser and luminescence programs.
Spatial construction on the beam and the corresponding intensity profiles I in the output with the laser.

Substantial-electricity repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical applications
While ytterbium-doped laser achieve media commonly show a small quantum defect, ytterbium-doped tungstates let for specifically smaller values. One example is, a 1030-nm Yb:YAG laser would Generally be pumped around 940 nm, whereas Yb:KGW or Yb:KYW may be most successfully pumped close to 981 nm.
Li2WO4-WO3 flux was properly utilized minimizing The expansion temperature below 900 oC. In line with solitary crystal x-ray measurements, the crystal corresponds to your P2/n Area team.
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) compared to its counterpart Yb:KGW, is actually a amazing substance that plays an important job in laser technologies. Its Major purpose should be to deliver ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
