The obtain bandwidth e.g. of Yb:KGW and Yb:KYW may be very big in comparison with that of Yb:YAG. This permits for huge wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values effectively below 100 fs have been attained with passive method locking.

This exceptional characteristic of ultrafast pulses permits nonlinear optical interaction with tissue at low In general publicity, and drives programs like deep-tissue multiphoton microscopy and superior-precision eye operation

This paper describes a femtosecond laser regenerative amplifier depending on two Yb:KYW crystals with immediate longitudinal pumping by highly effective linear arrays of semiconductor injection lasers acquiring fiber output. To forestall spectral narrowing through amplification plus the corresponding lengthening on the amplified pulse when it really is compressed, a combination of two Yb:KYW crystals were made use of, Along with the spectral maxima in the amplification shifted relative to each other and with spectral profiling of the amplified radiation.

The monoclinic crystal structures leads to a organic birefringence, helping to steer clear of thermally induced polarization rotation and depolarization loss.

PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and they are utilised as lasing components to produce ultrashort (~ a hundred-200 fs) large power pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes operating at 981 nm supports compact laser devices.

five mm other than the middle of the beam caustic. In an effort to check the manner matching simulation, we performed the experiment with Ng-Minimize crystal oscillator, which was made previously and in a exact same issue with simulation [11]. As proven in Figure 3(b) with red dots and line, the CW output electricity is extremely depending on the posture of laser crystal and also the experimental end result coincides very well with simulation end result. Like a Observe, multimode operation occurred in experiment in the event the sizing with the pump beam is much larger than TEM00 cavity method and it triggers bigger CW output electrical power inside the displacement location underneath 3.five mm.

By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW due to the identical measurements of these chemical things around a hundred% of Yb-doping may very well be attained.

Whilst ytterbium-doped laser obtain media normally exhibit a little quantum defect, ytterbium-doped tungstates allow for for particularly small values. For instance, a get more info 1030-nm Yb:YAG laser would Typically be pumped close to 940 nm, Whilst Yb:KGW or Yb:KYW can be most competently pumped all-around 981 nm.

The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at area temperature ended up calculated. The emission spectrum and life span from the 3 F 4 thrilled condition have been decided. Working with typical and modified Judd–Ofelt theories, the intensity parameters and also the radiative lifetimes had been calculated and excellent agreement With all the experimental final results was obtained for both theories.
