The comparison with glasses is acceptable Considering that the substantial achieve bandwidth permits e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
The Yb:KYW crystal’s proficiency in light absorption at all around 981 nm will make the crystal well suited for diode pumping. It really is even further Increased by its remarkable efficiency in this method, coupled with its small quantum defect.

This paper describes a femtosecond laser regenerative amplifier determined by two Yb:KYW crystals with direct longitudinal pumping by potent linear arrays of semiconductor injection lasers getting fiber output. To prevent spectral narrowing during amplification as well as corresponding lengthening with the amplified pulse when it truly is compressed, a combination of two Yb:KYW crystals ended up employed, Using the spectral maxima of your amplification shifted relative to each other and with spectral profiling from the amplified radiation.
After air drying and subsequent cleaning with a cotton cloth soaked in Alcoholic beverages, the film surface area confirmed no indications of peeling or scratches.

5 mm aside from the middle with the beam caustic. So as to Test the method matching simulation, we performed the experiment with Ng-cut crystal oscillator, which was made Earlier and in a exact issue with simulation [11]. As demonstrated in Figure three(b) with red dots and line, the CW output ability is extremely depending on the placement of laser crystal and the experimental consequence coincides well with simulation consequence. As being a Observe, multimode Procedure occurred in experiment if the sizing in the pump beam is larger sized than TEM00 cavity mode and it triggers better CW output power inside the displacement area underneath three.five mm.

... Don't just the position of crystal from the cavity but in addition the amplification axis of crystal impacts the laser Procedure considerably, because the absorption and emission cross sections on the crystal are pretty distinct in accordance with the orientation on the crystal.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison with its counterpart Yb:KGW, is actually a exceptional materials that plays an essential function in laser technological innovation. Its Principal perform is to deliver ultrashort pulses of light, spanning just a few hundred femtoseconds.
