The attain bandwidth e.g. of Yb:KGW and Yb:KYW is quite substantial compared with that of Yb:YAG. This allows for extensive wavelength tunability and for Substantially shorter pulse durations from manner-locked lasers. Values well beneath one hundred fs are actually achieved with passive manner locking.

time. Crystals of the compound melts congruently at 1007 oC, however melt crystallization of top of the range crystal is difficult resulting from period transition at ~920 oC. The highest seeded Remedy technique from

This paper describes a femtosecond laser regenerative amplifier based on two Yb:KYW crystals with immediate longitudinal pumping by powerful linear arrays of semiconductor injection lasers having fiber output. To stop spectral narrowing in the course of amplification and also the corresponding lengthening of the amplified pulse when it is actually compressed, a combination of two Yb:KYW crystals were applied, Together with the spectral maxima from the amplification shifted relative to each other and with spectral profiling with the amplified radiation.

Soon after air drying and subsequent cleaning that has a cotton cloth soaked in Liquor, the movie surface area confirmed no signs of peeling or scratches.

PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and so are employed as lasing components to produce ultrashort (~ a hundred-200 fs) high ability pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes operating at 981 nm supports compact laser devices.

Spatial structure of your beam as well as corresponding depth profiles I with the output in the laser.

By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW due to equivalent dimensions of those chemical components as many as 100% of Yb-doping can be reached.

The thermal conductivity of frequent double tungstates is of your purchase to three–4 W/(K m) �?which isn't undesirable compared with other laser crystals (Despite the fact that quite a few occasions below for YAG), and quite big in comparison Along with the thermal conductivity of usual Eyeglasses.

Li2WO4-WO3 flux was correctly used reducing the growth temperature below 900 oC. In accordance with solitary crystal x-ray measurements, the crystal corresponds for the P2/n Room team.
