The comparison with glasses is acceptable Considering that the substantial get bandwidth makes it possible for e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
time. Crystals with the compound melts congruently at 1007 oC, even so melt crystallization of top of the range crystal is difficult on account of stage changeover at ~920 oC. The highest seeded Answer process from
The absorption and emission spectra of Yb:KYW Crystals display strong peaks at 980 nm and 1030 nm, respectively, making sure efficient Vitality conversion and significant overall performance in laser methods.
This paper describes a femtosecond laser regenerative amplifier based on two Yb:KYW crystals with direct longitudinal pumping by potent linear arrays of semiconductor injection lasers acquiring fiber output. To circumvent spectral narrowing all through amplification plus the corresponding lengthening on the amplified pulse when it really is compressed, a combination of two Yb:KYW crystals were being utilised, With all the spectral maxima of the amplification shifted relative to one another and with spectral profiling in the amplified radiation.
The monoclinic crystal buildings ends in a normal birefringence, helping to steer clear of thermally induced polarization rotation and depolarization decline.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and are used as lasing elements to generate ultrashort (~ one hundred-200 fs) superior electric power pulses. Direct pump of Yb:KGW/KYW crystals with laser read more diodes functioning at 981 nm supports compact laser programs.
five mm besides the middle with the beam caustic. In an effort to Check out the mode matching simulation, we executed the experiment with Ng-Slash crystal oscillator, which was produced previously As well as in a very same problem with simulation [eleven]. As proven in Determine 3(b) with pink dots and line, the CW output electric power is highly depending on the position of laser crystal and the experimental consequence coincides nicely with simulation consequence. As being a Take note, multimode operation transpired in experiment when the measurement of your pump beam is greater than TEM00 cavity manner and it causes larger CW output electric power in the displacement region under three.five mm.

By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW due to the very similar sizes of such chemical factors up to one hundred% of Yb-doping may very well be reached.
