The get bandwidth e.g. of Yb:KGW and Yb:KYW is rather substantial when compared with that of Yb:YAG. This enables for huge wavelength tunability and for A great deal shorter pulse durations from method-locked lasers. Values properly under one hundred fs are actually accomplished with passive method locking.
The comparison with glasses is acceptable Considering that the large get bandwidth makes it possible for e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
We existing a twin-crystal Yb:KGW laserthat iscapable to operate being a Q-switched oscillator with output ability as many as 24 W and pulse length of twenty ns,or like a regenerative amplifier with output electrical power around 21 W and pulse duration down below 200 fs just after compression of chirped pulses. Both lasers have fantastic beam quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals display solid peaks at 980 nm and 1030 nm, respectively, ensuring economical energy conversion and high functionality in laser units.
This paper describes a femtosecond laser regenerative amplifier determined by two Yb:KYW crystals with immediate longitudinal pumping by impressive linear arrays of semiconductor injection lasers acquiring fiber output. To stop spectral narrowing during amplification plus the corresponding lengthening in the amplified pulse when it is compressed, a combination of two Yb:KYW crystals were being utilised, Using the spectral maxima with the amplification shifted relative to each other and with spectral profiling on the amplified radiation.
Just before the event of Nd:YAG, Nd3+:CaWO4 was a vital scarce-earth-doped laser achieve medium. It absolutely was actually Utilized in the 1st repeatedly running crystal laser.
Raman, luminescence and transmission spectra reveal optical functions owing on the presence of thulium ions, and as a consequence the elements could possibly be additional analyzed inside the scope of laser and luminescence purposes.
Tungstates have a tendency to own high Raman coefficients (�?Raman scattering). Consequently, they are able to deliver sizeable Raman achieve at average optical intensities. It is possible to make use of the laser crystal alone as a Raman converter.
... at fifty percent-top had been created inside a grasp oscillator with selfsynchronization of the axial modes, described inside our earlier report. 21 The new edition on the laser, contrary to that described in our previously post, made use of an Yb:KYW crystal by having read more an N pcut (optical axis N p from the index ellipsoid was parallel into the propagation route of the laser radiation), Along with the polarization in the created radiation directed along the N m axis.
Significant-energy repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical applications
