KYW Crystal - An Overview
Blog Article
In useful terms, the Yb:KYW crystal has identified its market in large-energy laser applications as a consequence of its ability to generate substantial Electricity ultrashort laser pulses while preserving a compact measurement. The interaction of its capabilities �?seamless ytterbium substitution, strong absorption attributes, ultrashort pulse technology and efficiency in Electricity conversion �?positions the Yb:KYW crystal as a cornerstone in the laser technological know-how, covering assorted fields ranging from scientific research to industrial programs.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, is usually a outstanding substance that plays an important job in laser technology. Its Key function is always to deliver ultrashort pulses of light, spanning just some hundred femtoseconds.
time. Crystals of your compound melts congruently at 1007 oC, on the other hand melt crystallization of high quality crystal is unachievable resulting from stage transition at ~920 oC. The highest seeded Remedy method from
The absorption and emission spectra of Yb:KYW Crystals Display screen strong peaks at 980 nm and 1030 nm, respectively, ensuring efficient Vitality conversion and large effectiveness in laser systems.
Optical structure of the laser with direct pumping While using the radiation of semiconductor injection lasers. LD is really an IPG Photonics laser diode with fiber output from the radiation, WP is usually a fifty percent-wave plate, CL is a collimating lens, FL can be a concentrating lens, AE is surely an Lively component comprised of an Yb:KYW crystal, DM is actually a spherical dichroic mirror, M1-M6 are definitely the cavity mirrors, OC may be the output mirror, and SAM is often a semiconductor saturable-absorber mirror.
Soon after air drying and subsequent cleansing using a cotton fabric soaked in alcohol, the film area showed no signs of peeling or scratches.
Raman, luminescence and transmission spectra expose optical functions owing for the existence of thulium ions, and so the elements might be even more examined in the scope of laser and luminescence applications.
5 mm apart from the middle on the beam caustic. So as to Test the method matching simulation, we done the experiment with Ng-Minimize crystal oscillator, which was designed Formerly As well as in a similar problem with simulation [11]. As revealed in Figure three(b) with crimson dots and line, the CW output energy is highly depending on the position of laser crystal and the experimental consequence coincides nicely with simulation final result. Like a Be aware, multimode Procedure occurred in experiment if the size on the pump beam is bigger than TEM00 cavity method and it will cause greater CW output ability inside the displacement area below 3.five mm.
... at fifty percent-peak were created in a learn oscillator with selfsynchronization of your axial modes, explained within our earlier write-up. 21 The new version of your read more laser, compared with that explained within our earlier article, applied an Yb:KYW crystal using an N pcut (optical axis N p from the index ellipsoid was parallel into the propagation route of the laser radiation), While using the polarization on the generated radiation directed alongside the N m axis.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW as a result of equivalent sizes of such chemical things approximately one hundred% of Yb-doping may be reached.

Li2WO4-WO3 flux was efficiently used lessening the growth temperature under 900 oC. According to single crystal x-ray measurements, the crystal corresponds on the P2/n Place team.
