The gain bandwidth e.g. of Yb:KGW and Yb:KYW is rather big when compared with that of Yb:YAG. This allows for vast wavelength tunability and for A great deal shorter pulse durations from method-locked lasers. Values very well down below a hundred fs have been realized with passive manner locking.

Femtosecond laser based upon Yb:KYW crystals with suppression of spectral narrowing in a regenerative amplifier by spectral profiling of the heartbeat
The absorption and emission spectra of Yb:KYW Crystals Display screen strong peaks at 980 nm and 1030 nm, respectively, ensuring effective Vitality conversion and large effectiveness in laser programs.
Ultrafast lasers, with pulse widths of some picoseconds (ten−12 s) or a lot less, help some time resolution required in laser-excited fluorescence life span spectroscopy and imaging tactics.Additionally, they deliver superior pulse peak powers at significant repetition charges and moderate normal output powers.
Adhesion Exam Compliant with MIL-C-675C military specifications, an adhesion examination included making use of a tape that fulfills LT-90 specifications onto the lens movie layer. The tape was affixed absolutely and after that taken off vertically. This technique was carried out three times, resulting in no blistering or peeling.
Raman, luminescence and transmission spectra expose optical capabilities owing towards the presence of thulium ions, and thus the products can be additional studied during the scope of laser and luminescence programs.

Substantial-ability repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical apps
Even though ytterbium-doped laser attain media usually exhibit a small quantum defect, ytterbium-doped tungstates permit more info for specifically modest values. One example is, a 1030-nm Yb:YAG laser would Commonly be pumped about 940 nm, whereas Yb:KGW or Yb:KYW could be most proficiently pumped all-around 981 nm.
Li2WO4-WO3 flux was successfully applied minimizing The expansion temperature below 900 oC. In accordance with solitary crystal x-ray measurements, the crystal corresponds to your P2/n House group.
