The obtain bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly massive when compared with that of Yb:YAG. This enables for extensive wavelength tunability and for Considerably shorter pulse durations from method-locked lasers. Values properly under one hundred fs have already been obtained with passive mode locking.

Femtosecond laser depending on Yb:KYW crystals with suppression of spectral narrowing within a regenerative amplifier by spectral profiling of the heartbeat
The absorption and emission spectra of Yb:KYW Crystals Show sturdy peaks at 980 nm and 1030 nm, respectively, making sure effective Strength conversion and superior efficiency in laser programs.
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW mainly because of the identical sizes of these chemical factors as much as one hundred% of Yb-doping can be realized. This special characteristic permits ytterbium to take the position of yttrium with just about no disruption on the crystal’s lattice.
Adhesion Check Compliant with MIL-C-675C military services specifications, an adhesion exam concerned implementing a tape that meets LT-90 specs on to the lens film layer. The tape was affixed totally and afterwards taken out vertically. This course of action was executed thrice, leading to no blistering or peeling.
Raman, luminescence and transmission spectra expose optical attributes owing to your existence of thulium ions, and for that reason the supplies could possibly be further more analyzed from the scope of laser and luminescence programs.
A superior brightnessQ-switched oscillator and regenerative amplifier according to a twin-crystal Yb:KGW laser
... at 50 %-peak more info ended up generated in the learn oscillator with selfsynchronization in the axial modes, explained inside our earlier report. 21 The new edition from the laser, contrary to that explained in our previously short article, used an Yb:KYW crystal using an N pcut (optical axis N p with the index ellipsoid was parallel to the propagation path with the laser radiation), with the polarization of the generated radiation directed alongside the N m axis.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared with its counterpart Yb:KGW, is actually a exceptional materials that plays an important job in laser technological know-how. Its Key purpose is always to produce ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
Concurrently, a shorter laser wavelength can be obtained; it is feasible to function that has a quantum defect perfectly below 1%. As being a consequence, the heat era could be so modest this partly compensates the decreased thermal conductivity.
