The obtain bandwidth e.g. of Yb:KGW and Yb:KYW may be very big compared with that of Yb:YAG. This permits for broad wavelength tunability and for Substantially shorter pulse durations from mode-locked lasers. Values well under a hundred fs have been accomplished with passive mode locking.
That is a preview of membership content, log in by using an establishment to check entry. Entry this information
The Yb:KYW crystal’s proficiency in light absorption at all over 981 nm can make the crystal compatible for diode pumping. It is even more Increased by its outstanding efficiency in this method, coupled with its lower quantum defect.
Colour-coded reflectivity of a Bragg mirror as a functionality of wavelength and angle on the incident beam.
Ultrafast lasers, with pulse widths of a few picoseconds (10−twelve s) or less, allow enough time resolution demanded in laser-energized fluorescence life time spectroscopy and imaging approaches.Additionally, they provide high pulse peak powers at superior repetition prices and moderate common output powers.
After air drying and subsequent cleaning with a cotton fabric soaked in alcohol, the film area showed no signs of peeling or scratches.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and they are used as lasing products to crank out ultrashort (~ one hundred-two hundred fs) significant energy pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes functioning at 981 nm supports compact laser programs.
A significant brightnessQ-switched oscillator and regenerative amplifier based upon a twin-crystal Yb:KGW laser
For tungstates, the ytterbium doping concentration can be quite high with no sizeable quenching because the replaced ions have an exceptionally comparable ion radius, plus the inter-ion distance is comparatively big.
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW mainly because of the identical measurements of these chemical things as many as one hundred% of Yb-doping might be accomplished.
