The attain bandwidth e.g. of Yb:KGW and Yb:KYW is rather significant in comparison with that of Yb:YAG. This permits for broad wavelength tunability and for A lot shorter pulse durations from manner-locked lasers. Values very well underneath 100 fs are accomplished with passive manner locking.

It is a preview of membership information, log in by way of an establishment to examine accessibility. Entry this informative article

time. Crystals from the compound melts congruently at 1007 oC, however melt crystallization of top quality crystal is not possible resulting from stage transition at ~920 oC. The top seeded Alternative process from

The absorption and emission spectra of Yb:KYW Crystals display robust peaks at 980 nm and 1030 nm, respectively, making sure efficient Electricity conversion and large overall performance in laser units.

This paper describes a femtosecond laser regenerative amplifier depending on two Yb:KYW crystals with immediate longitudinal pumping by strong linear arrays of semiconductor injection lasers acquiring fiber output. To avoid spectral narrowing for the duration of amplification and also the corresponding lengthening on the amplified pulse when it can be compressed, a mix of two Yb:KYW crystals have been made use of, With all the spectral maxima with the amplification shifted relative to one another and with spectral profiling of your amplified radiation.

In advance of the development of Nd:YAG, Nd3+:CaWO4 was a vital unusual-earth-doped laser achieve medium. It absolutely was in fact Utilized in the first consistently running crystal laser.

Spatial framework with the beam along with the corresponding depth profiles I within the output in the laser.

By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW as a result of very similar measurements of these chemical components up to a hundred% of Yb-doping may be reached.
