The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison to its counterpart Yb:KGW, is actually a extraordinary material that performs an essential purpose in laser technological know-how. Its Major operate is usually to generate ultrashort pulses of light, spanning just some hundred femtoseconds.
Femtosecond laser according to Yb:KYW crystals with suppression of spectral narrowing in a regenerative amplifier by spectral profiling of the pulse
Shade-coded reflectivity of a Bragg mirror to be a purpose of wavelength and angle in the incident beam.
Ultrafast lasers, with pulse widths of a few picoseconds (10−12 s) or considerably less, enable the time resolution needed in laser-psyched fluorescence life span spectroscopy and imaging strategies.Also, they produce high pulse peak powers at large repetition fees and moderate common output powers.
Right after air drying and subsequent cleansing having a cotton cloth soaked in Alcoholic beverages, the movie surface area showed no signs of peeling or scratches.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and are utilized as lasing materials to make ultrashort (~ a hundred-two hundred fs) higher power pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes running at 981 nm supports compact laser units.
five mm aside from the center of your beam caustic. To be able to Check out the manner matching simulation, we done the experiment with Ng-cut crystal oscillator, which was created Earlier and in a similar ailment with simulation [eleven]. As proven in Figure 3(b) with red dots and line, the CW output electricity is extremely depending on the place of laser crystal as well as the experimental consequence coincides perfectly with simulation result. As being a Take note, multimode Procedure happened in experiment in the event the size of the pump beam is bigger than TEM00 cavity mode and it will cause higher CW output energy within the displacement location underneath 3.five mm.
For tungstates, the ytterbium doping focus can be quite higher devoid of sizeable quenching because the changed ions have a very equivalent ion radius, as well as the inter-ion distance is fairly huge.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW due to the related dimensions of these chemical aspects approximately 100% of Yb-doping may be achieved.
Even though ytterbium-doped laser obtain media typically show a small quantum defect, ytterbium-doped tungstates allow for significantly modest values. As an example, a 1030-nm Yb:YAG laser would Usually be pumped around 940 nm, While Yb:KGW or Yb:KYW might be most successfully pumped around website 981 nm.
