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 wide wavelength tunability and for Significantly shorter pulse durations from method-locked lasers. Values well beneath 100 fs are obtained with passive manner locking.

Femtosecond laser according to Yb:KYW crystals with suppression of spectral narrowing in a very regenerative amplifier by spectral profiling of the heart beat
Should you be aiming to obtain This website working with an nameless Private/Proxy network, remember to disable that and check out accessing web page again.
This paper describes a femtosecond laser regenerative amplifier based on two Yb:KYW crystals with immediate longitudinal pumping by strong linear arrays of semiconductor injection lasers obtaining fiber output. To stop spectral narrowing throughout amplification and the corresponding lengthening with the amplified pulse when it really is compressed, a combination of two Yb:KYW crystals had been made use of, Together with the spectral maxima of your amplification shifted relative to each other and with spectral profiling of the amplified radiation.
The monoclinic crystal buildings leads to a organic birefringence, helping to avoid thermally induced polarization rotation and depolarization decline.

Tungstates are inclined to possess higher Raman coefficients (�?Raman scattering). Thus, they're able to create major Raman obtain at moderate optical intensities. It can be done to utilize the laser crystal alone like a Raman converter.

Large-ability repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical programs
The thermal conductivity of widespread double tungstates is from the get to three–4 W/(K m) �?which isn't poor as opposed with other laser crystals (Though quite a few instances fewer than for YAG), and relatively significant in contrast Along with the thermal conductivity of typical glasses.
Li2WO4-WO3 flux was effectively utilized cutting down The expansion temperature below 900 oC. In line with solitary crystal x-ray measurements, the crystal corresponds to your P2/n House team.
