The Yb:KYW crystal’s proficiency in gentle absorption at about 981 nm can make the crystal compatible for diode pumping. It can be even further Improved by its impressive performance in this method, coupled with its lower quantum defect.
Should you be aiming to entry This page employing an nameless Non-public/Proxy network, you should disable that and try accessing website all over again.
This paper describes a femtosecond laser regenerative amplifier according to two Yb:KYW crystals with direct longitudinal pumping by potent linear arrays of semiconductor injection lasers getting fiber output. To stop spectral narrowing in the course of amplification and also the corresponding lengthening from the amplified pulse when it really is compressed, a combination of two Yb:KYW crystals ended up applied, Along with the spectral maxima on the amplification shifted relative to each other and with spectral profiling of the amplified radiation.
Just after air drying and subsequent cleansing which has a cotton fabric soaked in alcohol, the movie surface area confirmed no signs of peeling or scratches.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and therefore are employed as lasing components to generate ultrashort (~ a hundred-200 fs) higher energy pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser techniques.
Spatial composition from the beam as well as the corresponding depth profiles I with the output on the laser.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared with its counterpart Yb:KGW, is often a impressive product that plays an essential purpose in laser technological know-how. Its Main function should be to produce ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
At the same time, a shorter laser wavelength may be received; it can be done to get more info work having a quantum defect effectively underneath one%. To be a consequence, the heat generation may be so modest this partly compensates the decreased thermal conductivity.
