Even though ytterbium-doped laser get media commonly show a small quantum defect, ytterbium-doped tungstates enable for specifically little values. For example, a 1030-nm Yb:YAG laser would normally be pumped around 940 nm, Whilst Yb:KGW or Yb:KYW may be most proficiently pumped close to 981 nm.

Hence There's minor flexibility for optimizing the dispersion payment effect. Sub-200 fs pulses can be expected that has a broader bandwidth seed enter. Thanks to the dual-crystal configuration, the laser cavity delivers a in the vicinity of diffraction limited laser beam with M

Amplified pulses using an Electrical power previously mentioned two.5 mJ might be expected by making use of an increased pump ability into the regenerative amplifier and making it perform with the saturation amount. The laser fluence of ~1 J/cm2 around the dichroic mirrors is believed for being beneath the injury threshold of large-high quality dielectric-coated mirrors.

Comparison of spectral Strength densities of supercontinua developed inside the disorders of best pumping during the investigated supplies.
Request RP Photonics for any information relating to tungstate lasers, which include femtosecond lasers and superior-energy lasers.
The brink Electrical power for SC generation (hbox E _ textrm th ) was described as being the pump pulse energy, the place the blue-shifted spectral broadening quickly settles to a particular Slice-off wavelength that remains Virtually frequent Despite further more improve on the pump pulse Electrical power. The optimum Vitality (hbox E _textrm choose ), was described given that get more info the pump pulse energy, which produces the largest red-shifted spectral broadening before the onset of periodic modulation within the SC spectrum on account of filament refocusing.

KGW has a robust Raman spectrum that extends through the ultraviolet to your around infrared, which makes it valuable for A variety of programs. The crystal can be utilized like a reference substance for Raman spectroscopy, in addition to a sample for researching Raman scattering within the sound state.
