The obtain bandwidth e.g. of Yb:KGW and Yb:KYW is rather large in comparison with that of Yb:YAG. This enables for wide wavelength tunability and for Significantly shorter pulse durations from method-locked lasers. Values very well below 100 fs have already been reached with passive method locking.
This exceptional characteristic of ultrafast pulses permits nonlinear optical interaction with tissue at minimal General publicity, and drives apps for example deep-tissue multiphoton microscopy and large-precision eye surgery
time. Crystals from the compound melts congruently at 1007 oC, on the other hand soften crystallization of high quality crystal is unachievable resulting from stage changeover at ~920 oC. The highest seeded solution approach from
The absorption and emission spectra of Yb:KYW Crystals Exhibit strong peaks at 980 nm and 1030 nm, respectively, making certain productive Power conversion and significant overall performance in laser techniques.
By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW due to the equivalent measurements of those chemical features as much as 100% of Yb-doping may be achieved. This special characteristic permits ytterbium to take the location of yttrium with almost no disruption to your crystal’s lattice.
Adhesion Exam Compliant with MIL-C-675C army expectations, an adhesion exam associated implementing a tape that satisfies LT-ninety technical specs on to the lens movie layer. The tape was affixed thoroughly after which you can removed vertically. This procedure was performed thrice, causing no blistering or peeling.

A higher brightnessQ-switched oscillator and regenerative amplifier depending on a dual-crystal Yb:KGW laser
... at 50 %-height were created inside of a grasp oscillator with selfsynchronization of the axial modes, explained in our earlier article. 21 The new edition from the laser, as opposed to that described within our previously short article, employed an Yb:KYW crystal with an N pcut (optical axis N p on the index ellipsoid was parallel for the propagation path from the laser radiation), Using the polarization of your produced radiation directed alongside the N m axis.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW as a result of similar dimensions of those chemical factors nearly one hundred% of Yb-doping may be attained.

The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)two) crystal at room temperature had been calculated. The emission spectrum and life span of your 3 F 4 fired up condition ended up identified. Using regular and modified Judd–Ofelt theories, the intensity parameters as well as the radiative lifetimes have been calculated and excellent arrangement Together with the experimental effects was received for both equally theories.
