The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly massive in comparison with that of Yb:YAG. This enables for vast wavelength tunability and for Significantly shorter pulse durations from mode-locked lasers. Values perfectly down below a hundred fs are attained with passive manner locking.
This exclusive attribute of ultrafast pulses allows nonlinear optical conversation with tissue at lower In general publicity, and drives purposes such as deep-tissue multiphoton microscopy and high-precision eye surgical procedure
time. Crystals on the compound melts congruently at 1007 oC, having said that melt crystallization of high quality crystal is impossible due to phase transition at ~920 oC. The top seeded Answer approach from
For anyone who is seeking to accessibility This website making use of an anonymous Non-public/Proxy network, you should disable that and take a look at accessing site once more.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW because of the identical measurements of those chemical elements around 100% of Yb-doping might be realized. This exceptional attribute permits ytterbium to take the location of yttrium with almost no disruption towards the crystal’s lattice.
Right after air drying and subsequent cleansing having a cotton fabric soaked in Liquor, the movie floor showed no indications of peeling or scratches.

5 mm in addition to the center with the beam caustic. So that you can Examine the method matching simulation, we performed the experiment with Ng-Lower crystal oscillator, which was developed Formerly As well as in a exact ailment with simulation [11]. As revealed in Figure 3(b) with pink dots and line, the CW output electrical power is very depending on the place of laser crystal as well as experimental outcome coincides properly with simulation final result. Like a Observe, multimode Procedure occurred in experiment once the measurement of your pump beam is bigger than TEM00 cavity method and it will cause higher CW output ability inside the displacement area down below three.five mm.
... at fifty percent-top had been produced in a grasp oscillator with selfsynchronization of your axial modes, described within our before post. 21 The new edition of your laser, as opposed to that explained inside our earlier write-up, used an Yb:KYW crystal by having an N pcut (optical axis N p with the index ellipsoid was parallel towards the propagation direction of your laser radiation), Using the polarization of the generated radiation directed alongside the N m axis.
By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW a result of the equivalent sizes of these chemical elements up to a hundred% of Yb-doping may very well be accomplished.
The thermal conductivity of frequent double tungstates is from the get to 3–4 W/(K m) �?which isn't negative in contrast with other laser crystals (although various instances less than for YAG), and rather huge more info compared Along with the thermal conductivity of standard Eyeglasses.
This tandem of attributes has much-reaching implications, notably in the development of compact still powerfull lasers.
