The get bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly large in comparison with that of Yb:YAG. This enables for large wavelength tunability and for Significantly shorter pulse durations from method-locked lasers. Values very well down below a hundred fs happen to be attained with passive mode locking.
This unique characteristic of ultrafast pulses enables nonlinear optical conversation with tissue at minimal All round exposure, and drives programs including deep-tissue multiphoton microscopy and superior-precision eye operation
Femtosecond laser based on Yb:KYW crystals with suppression of spectral narrowing within a regenerative amplifier by spectral profiling of the heart beat
The absorption and emission spectra of Yb:KYW Crystals Show sturdy peaks at 980 nm and 1030 nm, respectively, guaranteeing economical Power conversion and substantial general performance in laser systems.
By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW because of the equivalent measurements of those chemical things nearly a hundred% of Yb-doping could be accomplished. This distinctive characteristic permits ytterbium to go ahead and take put of yttrium with virtually no disruption to the crystal’s lattice.
The monoclinic crystal constructions ends in a pure birefringence, assisting to keep away from thermally induced polarization rotation and depolarization reduction.
Raman, luminescence and transmission spectra expose optical features owing for the presence of thulium ions, and so the elements could be further more researched inside the scope of laser and luminescence programs.
Spatial structure of the beam along with the corresponding intensity profiles I within the output with the laser.

Having said that, when Nd3+:YAG grew to become commercially out there, the curiosity in CaWO4 dropped sharply. In later on yrs, certain other tungstate crystals started to KYW Crystal appeal to a great deal of notice.

Concurrently, a shorter laser wavelength might be acquired; it can be done to function by using a quantum defect effectively down below 1%. As a consequence, the warmth technology might be so little this partly compensates the lower thermal conductivity.
