The obtain bandwidth e.g. of Yb:KGW and Yb:KYW may be very big when compared with that of Yb:YAG. This permits for wide wavelength tunability and for Considerably shorter pulse durations from manner-locked lasers. Values well beneath 100 fs are already realized with passive manner locking.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, is really a remarkable product that plays an essential function in laser technologies. Its primary functionality is usually to make ultrashort pulses of light, spanning just a couple hundred femtoseconds.
The Yb:KYW crystal’s proficiency in gentle absorption at all-around 981 nm makes the crystal well suited for diode pumping. It is actually even further enhanced by its exceptional efficiency in this method, coupled with its reduced quantum defect.
Coloration-coded reflectivity of a Bragg mirror like a perform of wavelength and angle from the incident beam.
This paper describes a femtosecond laser regenerative amplifier based upon two Yb:KYW crystals with direct longitudinal pumping by impressive linear arrays of semiconductor injection lasers obtaining fiber output. To prevent spectral narrowing all through amplification as well as the corresponding lengthening of the amplified pulse when it is actually compressed, a combination of two Yb:KYW crystals ended up utilized, Along with the spectral maxima from the amplification shifted relative to each other and with spectral profiling with the amplified radiation.
Before the development of Nd:YAG, Nd3+:CaWO4 was a very important uncommon-earth-doped laser achieve medium. It absolutely was in actual fact Employed in the main continuously functioning crystal laser.

By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW because of the comparable dimensions of those chemical components up to one hundred% of Yb-doping could possibly be accomplished.
