While ytterbium-doped laser gain media generally show a small quantum defect, ytterbium-doped tungstates enable for specifically smaller values. Such as, a 1030-nm Yb:YAG laser would normally be pumped all around 940 nm, Whilst Yb:KGW or Yb:KYW may very well be most effectively pumped all around 981 nm.
The attain bandwidth e.g. of Yb:KGW and Yb:KYW is quite massive in comparison with that of Yb:YAG. This enables for huge wavelength tunability and for Considerably shorter pulse durations from method-locked lasers. Values effectively under 100 fs happen to be obtained with passive manner locking.
Therefore You can find little liberty for optimizing the dispersion compensation impact. Sub-200 fs pulses is often predicted by using a broader bandwidth seed input. Due to the twin-crystal configuration, the laser cavity provides a near diffraction limited laser beam with M
Its pump laser requires a short pulse duration, a low time jitter, and smooth temporal and spatial distributions due to the intrinsic instantaneous method. As a result, the OPCPA process is much more complex and pricey.
The calculated Minimize-off wavelengths within the short-wavelength aspect are in step with the general craze of blue-shifted spectral broadening about the bandgap of nonlinear materials. Every one of the nonlinear elements manufactured sensible purple-shifted spectral broadenings below conditions of best pump pulse energies, with the most important crimson-shift exceeding 2000 nm calculated in GGG crystal. Our success revealed that GGG and BGO (which also had the lowest supercontinuum era threshold) give strong, optical destruction-cost-free performance in a laser repetition level of two hundred kHz, suggesting that these elements are superior solutions to YAG and KGW for low threshold, large KGW Crystal normal electrical power supercontinuum era within the close to- and shorter-wave infrared spectral ranges. We also demonstrated that scintillating Attributes of bulk materials can be conveniently studied inside the filamentation routine, by way of multiphoton excitation employing in close proximity to-infrared femtosecond laser pulses.

The black line denotes the configuration Using the crystals placed in the same orientation, when the red line is underneath the configuration of crystals put in orthogonal orientation.
