The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is extremely big in contrast with that of Yb:YAG. This allows for wide wavelength tunability and for A lot shorter pulse durations from mode-locked lasers. Values well down below a hundred fs have already been achieved with passive manner locking.
This one of a kind characteristic of ultrafast pulses enables nonlinear optical interaction with tissue at reduced All round exposure, and drives apps for instance deep-tissue multiphoton microscopy and large-precision eye medical procedures
The Yb:KYW crystal’s proficiency in light-weight absorption at all-around 981 nm makes the crystal well suited for diode pumping. It is additional enhanced by its exceptional efficiency in this method, coupled with its reduced quantum defect.
The absorption and emission spectra of Yb:KYW Crystals Exhibit strong peaks at 980 nm and 1030 nm, respectively, ensuring economical energy conversion and large efficiency in laser devices.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW because of the similar dimensions of these chemical features as many as 100% of Yb-doping may very well be reached. This exceptional attribute permits ytterbium to take the location of yttrium with just about no disruption into the crystal’s lattice.
Adhesion Exam Compliant with MIL-C-675C military specifications, an adhesion examination concerned implementing a tape that fulfills LT-90 technical specs on to the lens film layer. The tape was affixed completely and after that removed vertically. This course of action was performed thrice, leading to no blistering or peeling.

Spatial composition of your beam as well as corresponding depth profiles I within the output of your get more info laser.
For tungstates, the ytterbium doping concentration can be extremely significant with no substantial quenching as the replaced ions have a really similar ion radius, plus the inter-ion distance is pretty massive.
By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW a result of the equivalent sizes of such chemical features as many as one hundred% of Yb-doping could possibly be accomplished.
