Femtosecond laser depending on Yb:KYW crystals with suppression of spectral narrowing in a regenerative amplifier by spectral profiling of the heartbeat
Colour-coded reflectivity of the Bragg mirror as being a perform of wavelength and angle in the incident beam.
This paper describes a femtosecond laser regenerative amplifier depending on two Yb:KYW crystals with direct longitudinal pumping by potent linear arrays of semiconductor injection lasers having fiber output. To circumvent spectral narrowing all through amplification and the corresponding lengthening of the amplified pulse when it is compressed, a combination of two Yb:KYW crystals ended up utilized, Along with the spectral maxima on the amplification shifted relative to one another and with spectral profiling of the amplified radiation.
The monoclinic crystal structures ends in a normal birefringence, helping to stay away from thermally induced polarization rotation and depolarization decline.
Raman, luminescence and transmission spectra reveal optical attributes owing on the existence of thulium ions, and as a consequence the resources could be even more examined in the scope of laser and luminescence apps.
5 mm besides the center from the beam caustic. To be able to Verify the manner matching simulation, we carried out the experiment with Ng-Lower crystal oscillator, which was designed Beforehand As well as in a identical issue with simulation [eleven]. As revealed in Figure 3(b) with red dots and line, the CW output power is highly depending on the position of laser crystal as well as the experimental end result coincides perfectly with simulation end result. As a Notice, multimode Procedure transpired in experiment if the dimensions of the pump beam is larger sized than TEM00 cavity manner and it brings about better CW output electric power from the displacement region below 3.five mm.
... at 50 percent-height were being created within a learn oscillator with selfsynchronization of the axial modes, described within our previously write-up. 21 The new version with the laser, in contrast to that explained inside our previously posting, applied an Yb:KYW crystal with an N pcut (optical axis N p of the index ellipsoid was parallel to your propagation direction in the laser radiation), With all the polarization of your produced radiation directed alongside the N m axis.
By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW mainly because of the equivalent measurements of such chemical components approximately 100% of Yb-doping could be achieved.
The thermal conductivity of typical double tungstates is of the buy to read more three–4 W/(K m) �?which isn't terrible as opposed with other laser crystals (While a number of periods below for YAG), and fairly substantial in comparison While using the thermal conductivity of regular glasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison with its counterpart Yb:KGW, is actually a outstanding material that performs a significant job in laser technological know-how. Its Principal operate is always to crank out ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
