time. Crystals of your compound melts congruently at 1007 oC, on the other hand melt crystallization of high quality crystal is unachievable resulting from phase changeover at ~920 oC. The top seeded Remedy process from
Shade-coded reflectivity of the Bragg mirror as a perform of wavelength and angle in the incident beam.
This paper describes a femtosecond laser regenerative amplifier based on two Yb:KYW crystals with immediate longitudinal pumping by effective linear arrays of semiconductor injection lasers obtaining fiber output. To avoid spectral narrowing in the course of amplification as well as the corresponding lengthening from the amplified pulse when it is actually compressed, a combination of two Yb:KYW crystals had been used, Along with the spectral maxima in the amplification shifted relative to one another and with spectral profiling on the amplified radiation.
The monoclinic crystal buildings ends in a normal birefringence, helping to steer clear of thermally induced polarization rotation and depolarization loss.
Raman, luminescence and transmission spectra expose optical features owing for the presence of thulium ions, and therefore the components may very well be further more examined during the scope of laser and luminescence purposes.
Tungstates are likely to have higher Raman coefficients (�?Raman scattering). For that reason, they could deliver significant Raman acquire at moderate optical intensities. It is possible to utilize the laser crystal alone to be a Raman converter.
For tungstates, the ytterbium doping focus can be very superior with no significant quenching because the replaced ions have an exceedingly equivalent ion radius, plus the inter-ion length is relatively big.
... Not merely the posture of crystal in the cavity but additionally the amplification axis of crystal affects the laser operation drastically, since the absorption and emission cross sections in the crystal are really various according to the orientation of the crystal.
