The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly big compared with that of Yb:YAG. This permits for vast wavelength tunability and for Considerably shorter pulse durations from method-locked lasers. Values well down below one hundred fs happen to be achieved with passive method locking.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, compared to its counterpart Yb:KGW, is often a outstanding materials that plays a significant part in laser technological know-how. Its Key perform will be to generate ultrashort pulses of light, spanning just a couple hundred femtoseconds.
time. Crystals on the compound melts congruently at 1007 oC, having said that melt crystallization of high quality crystal is unattainable on account of period transition at ~920 oC. The very best seeded Remedy approach from
FIG. four. Autocorrelation purpose of the heartbeat 共a兲and spectrum 共b兲of the laser with an oblong Energetic component for an output electrical power of 700 mW. The width of
This paper describes a femtosecond laser regenerative amplifier according to two Yb:KYW crystals with direct longitudinal pumping by effective linear arrays of semiconductor injection lasers getting fiber output. To forestall spectral narrowing throughout amplification and the corresponding lengthening of the amplified pulse when it really is compressed, a mix of two Yb:KYW crystals had been utilised, With all the spectral maxima in the amplification shifted relative to one another and with spectral profiling of the amplified radiation.
Just before the event of Nd:YAG, Nd3+:CaWO4 was a vital exceptional-earth-doped laser acquire medium. It absolutely was in truth Employed in the 1st continuously running crystal laser.

Superior-electric power repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical apps
Although ytterbium-doped laser obtain media frequently show a little quantum defect, ytterbium-doped tungstates permit for specially tiny values. One example is, a 1030-nm click here Yb:YAG laser would Generally be pumped around 940 nm, whereas Yb:KGW or Yb:KYW could be most proficiently pumped all-around 981 nm.
This tandem of characteristics has much-reaching implications, specifically in the development of compact yet powerfull lasers.
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison with its counterpart Yb:KGW, is really a impressive substance that plays a vital purpose in laser know-how. Its Most important functionality is always to make ultrashort pulses of light, spanning only a few hundred femtoseconds.
