The attain bandwidth e.g. of Yb:KGW and Yb:KYW is extremely huge as opposed with that of Yb:YAG. This permits for extensive wavelength tunability and for much shorter pulse durations from method-locked lasers. Values well below one hundred fs have been achieved with passive method locking.

That is a preview of subscription information, log in by way of an institution to examine obtain. Entry this informative article

The Yb:KYW crystal’s proficiency in mild absorption at close to 981 nm will make the crystal well matched for diode pumping. It really is even further enhanced by its extraordinary effectiveness in this process, coupled with its lower quantum defect.

This paper describes a femtosecond laser regenerative amplifier based upon two Yb:KYW crystals with direct longitudinal pumping by highly effective linear arrays of semiconductor injection lasers owning fiber output. To stop spectral narrowing all through amplification and the corresponding lengthening on the amplified pulse when it can be compressed, a mix of two Yb:KYW crystals had been applied, While using the spectral maxima of the amplification shifted relative to one another and with spectral profiling in the amplified radiation.

Adhesion Take a look at Compliant with MIL-C-675C military services criteria, an adhesion take a look at included making use of a tape that satisfies LT-ninety technical specs onto the lens movie layer. The tape was affixed absolutely and then removed vertically. This treatment was done thrice, click here resulting in no blistering or peeling.

PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and they are made use of as lasing products to crank out ultrashort (~ one hundred-200 fs) high ability pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser techniques.

A superior brightnessQ-switched oscillator and regenerative amplifier based on a twin-crystal Yb:KGW laser

For tungstates, the ytterbium doping concentration can be quite higher without the need of considerable quenching since the changed ions have a really comparable ion radius, as well as inter-ion length is pretty huge.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) as compared to its counterpart Yb:KGW, is a impressive content that plays a vital position in laser technological know-how. Its Most important operate is usually to create ultrashort pulses of light, spanning just a few hundred femtoseconds.

At the same time, a shorter laser wavelength can be attained; it is feasible to operate that has a quantum defect effectively below one%. As being a consequence, the warmth generation is often so little this partly compensates the reduced thermal conductivity.
