In sensible terms, the Yb:KYW crystal has identified its market in substantial-electricity laser programs on account of its capability to create large Vitality ultrashort laser pulses whilst retaining a compact dimension. The interplay of its functions �?seamless ytterbium substitution, strong absorption characteristics, ultrashort pulse era and efficiency in Power conversion �?positions the Yb:KYW crystal for a cornerstone during the laser technology, covering assorted fields starting from scientific study to industrial purposes.
The comparison with Eyeglasses is suitable Because the big gain bandwidth permits e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
The Yb:KYW crystal’s proficiency in light-weight absorption at about 981 nm can make the crystal well matched for diode pumping. It's even more Improved by its remarkable efficiency in this process, coupled with its minimal quantum defect.
FIG. four. Autocorrelation operate of the pulse 共a兲and spectrum 共b兲of a laser with an oblong active aspect for an output energy of seven hundred mW. The width of
This paper describes a femtosecond laser regenerative amplifier depending on two Yb:KYW crystals with immediate longitudinal pumping by highly effective linear arrays of semiconductor injection lasers obtaining fiber output. To avoid spectral narrowing in the course of amplification and also the corresponding lengthening of the amplified pulse when it is actually compressed, a combination of two Yb:KYW crystals were applied, Together with the spectral maxima from the amplification shifted relative to one another and with spectral profiling from the amplified radiation.
Right before the development of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser obtain medium. It absolutely was in fact used in the 1st continuously operating crystal laser.
