The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared to its counterpart Yb:KGW, can be a amazing product that performs a very important role in laser technologies. Its Major perform is always to produce ultrashort pulses of light, spanning just a few hundred femtoseconds.
Femtosecond laser according to Yb:KYW crystals with suppression of spectral narrowing in a very regenerative amplifier by spectral profiling of the heart beat
The absorption and emission spectra of Yb:KYW Crystals display solid peaks at 980 nm and 1030 nm, respectively, making sure efficient Power conversion and large general performance in laser systems.
Optical structure of the laser with direct pumping Using the radiation of semiconductor injection lasers. LD can be an IPG Photonics laser diode with fiber output on the radiation, WP is really a 50 percent-wave plate, CL is actually a collimating lens, FL is usually a focusing lens, AE is really an active factor comprised of an Yb:KYW crystal, DM is really a spherical dichroic mirror, M1-M6 are definitely the cavity mirrors, OC could be the output mirror, and SAM is a semiconductor saturable-absorber mirror.
Adhesion Examination Compliant with MIL-C-675C military specifications, an adhesion take a look at included implementing a tape that satisfies LT-90 specifications onto the lens movie layer. The tape was affixed fully and after that eliminated vertically. This method was carried out three times, causing no blistering or peeling.
Raman, luminescence and transmission spectra expose optical functions owing to your existence of thulium ions, and therefore the supplies could possibly be more analyzed while in the scope of laser and luminescence programs.
A substantial brightnessQ-switched oscillator and regenerative amplifier determined by a dual-crystal Yb:KGW laser
For tungstates, the ytterbium doping concentration can be extremely substantial with no sizeable quenching since the replaced ions have an exceptionally comparable ion radius, along with the inter-ion length is relatively huge.
Higher-electrical power repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical apps
There aren't any objects in the cart. Add things to the cart and ask for an Formal estimate or buy on the net Subtotal
Li2WO4-WO3 flux was correctly applied lowering The expansion temperature click here down below 900 oC. Based on single crystal x-ray measurements, the crystal corresponds on the P2/n Place team.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at space temperature ended up calculated. The emission spectrum and life span of the 3 F 4 enthusiastic point out were being determined. Utilizing regular and modified Judd–Ofelt theories, the depth parameters as well as radiative lifetimes were being calculated and good agreement with the experimental outcomes was obtained for both theories.
Right here you may submit issues and feedback. As far as they get acknowledged because of the creator, they are going to show up higher than this paragraph together with the author’s reply. The writer will make a decision on acceptance dependant on particular requirements. Primarily, The problem have to be of sufficiently broad curiosity.
