The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, compared to its counterpart Yb:KGW, is usually a remarkable materials that plays a significant position in laser technology. Its Most important purpose is always to generate ultrashort pulses of light, spanning just a few hundred femtoseconds.
We current a dual-crystal Yb:KGW laserthat iscapable to function as a Q-switched oscillator with output power around 24 W and pulse duration of twenty ns,or like a regenerative amplifier with output electric power as many as 21 W and pulse length down below 200 fs just after compression of chirped pulses. Equally lasers have superb beam high quality with beam parameter M2

This paper describes a femtosecond laser regenerative amplifier determined by two Yb:KYW crystals with immediate longitudinal pumping by strong linear arrays of semiconductor injection lasers getting fiber output. To forestall spectral narrowing in the course of amplification and the corresponding lengthening in the amplified pulse when it is compressed, a combination of two Yb:KYW crystals had been made use of, Together with the spectral maxima from the amplification shifted relative to one another and with spectral profiling of the amplified radiation.
Soon after air drying and subsequent cleansing using a cotton fabric soaked in Alcoholic beverages, the film floor confirmed no signs of peeling or scratches.

... at fifty percent-peak had been generated in the grasp oscillator with selfsynchronization on the axial modes, described inside our earlier write-up. 21 The new version of your laser, in contrast to that described inside our earlier write-up, utilised an Yb:KYW crystal by having an N pcut (optical axis N p of your index ellipsoid was parallel towards the propagation direction with click here the laser radiation), With all the polarization of your generated radiation directed together the N m axis.
Having said that, after Nd3+:YAG grew to become commercially readily available, the interest in CaWO4 dropped sharply. In later several years, sure other tungstate crystals began to attract lots of interest.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, is a remarkable product that performs a vital part in laser technological innovation. Its Key functionality is usually to create ultrashort pulses of light, spanning just some hundred femtoseconds.
