The get bandwidth e.g. of Yb:KGW and Yb:KYW may be very large compared with that of Yb:YAG. This allows for broad wavelength tunability and for A lot shorter pulse durations from mode-locked lasers. Values nicely beneath 100 fs have already been obtained with passive method locking.
This exclusive attribute of ultrafast pulses allows nonlinear optical conversation with tissue at very low In general publicity, and drives purposes such as deep-tissue multiphoton microscopy and higher-precision eye surgical procedures
Femtosecond laser determined by Yb:KYW crystals with suppression of spectral narrowing in a very regenerative amplifier by spectral profiling of the heart beat

Ultrafast lasers, with pulse widths of some picoseconds (10−twelve s) or considerably less, empower the time resolution needed in laser-excited fluorescence lifetime spectroscopy and imaging tactics.Also, they supply significant pulse peak powers at superior repetition costs and reasonable regular output powers.
The monoclinic crystal buildings results in a all-natural birefringence, helping to stay away from thermally induced polarization rotation and depolarization reduction.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and so are applied as lasing materials to produce ultrashort (~ 100-200 fs) higher power pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes running at 981 nm supports compact laser systems.
Spatial structure of the beam and the corresponding intensity profiles I at the output of your laser.

Large-electric power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical applications
The thermal conductivity of widespread double tungstates is in the order to three–four W/(K m) �?which is not bad as opposed with other laser crystals (While numerous occasions less than for YAG), and rather massive in contrast with the thermal conductivity of regular glasses.
