The obtain bandwidth e.g. of Yb:KGW and Yb:KYW is quite huge in comparison with that of Yb:YAG. This allows for wide wavelength tunability and for A lot shorter pulse durations from mode-locked lasers. Values well underneath 100 fs happen to be achieved with passive manner locking.
The comparison with Eyeglasses is suitable For the reason that massive 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 as being a Q-switched oscillator with output electricity nearly 24 W and pulse duration of twenty ns,or like a regenerative amplifier with output ability around 21 W and pulse length underneath 200 fs following compression of chirped pulses. The two lasers have fantastic beam high quality with beam parameter M2
FIG. four. Autocorrelation function of the heartbeat 共a兲and spectrum 共b兲of the laser with a rectangular active factor for an output electric power of seven-hundred mW. The width of
Optical structure of the laser with direct pumping With all the radiation of semiconductor injection lasers. LD is an IPG Photonics laser diode with fiber output in the radiation, WP is usually a half-wave plate, CL is actually a collimating lens, FL can be a concentrating lens, AE can be an Lively ingredient comprised of an Yb:KYW crystal, DM is a spherical dichroic mirror, M1-M6 will be the cavity mirrors, OC could be the output mirror, and SAM is usually a semiconductor saturable-absorber mirror.
Soon after air drying and subsequent cleansing having a cotton cloth soaked in Alcoholic beverages, the movie surface showed no signs of peeling or scratches.

Tungstates are likely to obtain substantial Raman coefficients (�?Raman scattering). As a result, they will crank out considerable Raman attain at average optical intensities. It is achievable to use the laser crystal by itself to be a Raman converter.
... at 50 percent-top were being produced inside a learn oscillator with selfsynchronization in the axial modes, described inside our previously write-up. 21 The new version with the laser, contrary to that described inside our previously posting, utilised an Yb:KYW crystal with the N pcut (optical axis N p read more of your index ellipsoid was parallel for the propagation direction in the laser radiation), with the polarization on the created radiation directed along the N m axis.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW as a result of comparable dimensions of those chemical factors as much as a hundred% of Yb-doping may be accomplished.
Even though ytterbium-doped laser get media commonly show a small quantum defect, ytterbium-doped tungstates let for specially smaller values. As an example, a 1030-nm Yb:YAG laser would Commonly be pumped about 940 nm, Whilst Yb:KGW or Yb:KYW may be most competently pumped all around 981 nm.

The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at home temperature have been calculated. The emission spectrum and lifetime with the 3 File four excited condition were being established. Applying normal and modified Judd–Ofelt theories, the depth parameters and also the radiative lifetimes have been calculated and superior settlement Using the experimental benefits was attained for both theories.
