The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared to its counterpart Yb:KGW, is a impressive product that plays a vital job in laser engineering. Its Principal functionality is usually to generate ultrashort pulses of light, spanning only a few hundred femtoseconds.
Femtosecond laser depending on Yb:KYW crystals with suppression of spectral narrowing in a regenerative amplifier by spectral profiling of the pulse

This paper describes a femtosecond laser regenerative amplifier determined by two Yb:KYW crystals with immediate longitudinal pumping by powerful linear arrays of semiconductor injection lasers owning fiber output. To prevent spectral narrowing for the duration of amplification as well as corresponding lengthening in the amplified pulse when it is actually compressed, a combination of two Yb:KYW crystals have been utilised, With all the spectral maxima in the amplification shifted relative to each other and with spectral profiling on the amplified radiation.
Ahead of the development of Nd:YAG, Nd3+:CaWO4 was a very important unusual-earth-doped laser obtain medium. It had been in fact Utilized in the primary continually operating crystal laser.
Raman, luminescence and transmission spectra expose optical characteristics owing towards the existence of thulium ions, and so the supplies can be even more studied during the scope of laser and luminescence programs.
Spatial composition of the beam plus the corresponding depth profiles I on the output on the laser.
For tungstates, the ytterbium doping concentration can be extremely significant devoid of important quenching as the changed ions have an incredibly equivalent ion radius, and also the inter-ion length is fairly big.
Higher-electricity repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical purposes
Because of Earlier detected destructive behavior which originated from your community you are employing, be sure to request unblock to web site.
Li2WO4-WO3 flux was correctly used lessening The expansion temperature down below 900 oC. According to single crystal x-ray measurements, the crystal corresponds to the P2/n check here space team.
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison with its counterpart Yb:KGW, is actually a outstanding materials that performs a very important purpose in laser know-how. Its Principal perform would be to deliver ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
