The gain bandwidth e.g. of Yb:KGW and Yb:KYW is rather big compared with that of Yb:YAG. This enables for large wavelength tunability and for Considerably shorter pulse durations from method-locked lasers. Values properly underneath a hundred fs happen to be attained with passive method locking.

This distinctive attribute of ultrafast pulses allows nonlinear optical conversation with tissue at very low Total exposure, and drives apps for example deep-tissue multiphoton microscopy and large-precision eye surgical procedure

Femtosecond laser based upon Yb:KYW crystals with suppression of spectral narrowing inside a regenerative amplifier by spectral profiling of the heart beat

The absorption and emission spectra of Yb:KYW Crystals Screen solid peaks at 980 nm and 1030 nm, respectively, making sure economical energy conversion and higher efficiency in laser programs.

Optical format of the laser with direct pumping Using the radiation of semiconductor injection lasers. LD is an IPG Photonics laser diode with fiber output on the radiation, WP is really a 50 %-wave plate, CL is really a collimating lens, FL can be a concentrating lens, AE is an active element created from an Yb:KYW crystal, DM is usually a spherical dichroic mirror, M1-M6 will be the cavity mirrors, OC is definitely the output mirror, and SAM is really a semiconductor saturable-absorber mirror.

Adhesion Check Compliant with MIL-C-675C armed forces expectations, an adhesion exam included implementing a tape that fulfills LT-ninety technical specs on to the lens movie layer. The tape was affixed fully after which taken off vertically. This course of action was executed thrice, causing no blistering or peeling.

PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and are applied as lasing elements to make ultrashort (~ 100-two hundred fs) large energy pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser systems.

5 mm aside from the middle with the beam caustic. In an effort to Check out the method matching simulation, we performed the experiment with Ng-Slash crystal oscillator, which was developed Beforehand As well as in a same issue with simulation [11]. As revealed in Figure 3(b) with purple dots and line, the CW output electrical power is highly depending on the place of laser crystal and the experimental consequence coincides nicely with simulation final result. Being a Be aware, multimode Procedure happened in experiment if the sizing in the pump beam is much larger than TEM00 cavity mode and it triggers increased CW output ability within the displacement area underneath three.five mm.

For tungstates, KYW Crystal the ytterbium doping concentration can be quite high with no sizeable quenching because the replaced ions have an exceptionally similar ion radius, as well as the inter-ion length is pretty large.

Superior-power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical applications

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared to its counterpart Yb:KGW, is usually a extraordinary product that performs a vital part in laser engineering. Its Main function should be to crank out ultrashort pulses of light, spanning just some hundred femtoseconds.

Inquire RP Photonics for virtually any tips concerning tungstate lasers, together with femtosecond lasers and substantial-power lasers.
