The gain bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly large in contrast with that of Yb:YAG. This enables for wide wavelength tunability and for Considerably shorter pulse durations from method-locked lasers. Values perfectly below 100 fs have already been reached with passive method locking.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, is usually a outstanding content that performs an important function in laser technological know-how. Its Main perform is always to deliver ultrashort pulses of light, spanning just a couple hundred femtoseconds.
The Yb:KYW crystal’s proficiency in light absorption at close to 981 nm would make the crystal well matched for diode pumping. It's even more Improved by its extraordinary performance in this method, coupled with its small quantum defect.

This paper describes a femtosecond laser regenerative amplifier based 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 all through amplification and also the corresponding lengthening from the amplified pulse when it is actually compressed, a mix of two Yb:KYW crystals ended up utilized, with the spectral maxima of the amplification shifted relative to one another and with spectral profiling in the amplified radiation.
Ahead of the development of Nd:YAG, Nd3+:CaWO4 was a vital uncommon-earth-doped laser achieve medium. It was the truth is Employed in the initial repeatedly operating crystal laser.
FIG. one. Optical format of the laser with direct pumping While using the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output
Tungstates are inclined to possess substantial Raman coefficients (�?Raman scattering). Hence, they are able to make major Raman attain at average optical intensities. It is possible to utilize the laser crystal alone being a Raman converter.

By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW because of the related measurements of such chemical features as many as 100% of Yb-doping may be obtained.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared with its counterpart Yb:KGW, is often a extraordinary material that performs an more info important role in laser technology. Its primary functionality will be to make ultrashort pulses of light, spanning just some hundred femtoseconds.
