The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is extremely substantial as opposed with that of Yb:YAG. This permits for extensive wavelength tunability and for A great deal shorter pulse durations from manner-locked lasers. Values perfectly underneath 100 fs are accomplished with passive manner locking.
The comparison with glasses is acceptable For the reason that big obtain bandwidth lets e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
time. Crystals of your compound melts congruently at 1007 oC, nevertheless soften crystallization of top of the range crystal is unachievable as a consequence of section transition at ~920 oC. The best seeded Alternative technique from
The absorption and emission spectra of Yb:KYW Crystals display powerful peaks at 980 nm and 1030 nm, respectively, ensuring productive energy conversion and substantial effectiveness in laser systems.
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW due to similar measurements of these chemical things approximately 100% of Yb-doping can be realized. This unique characteristic permits ytterbium to take the position of yttrium with pretty much no disruption towards the crystal’s lattice.
Immediately after air drying and subsequent cleansing having a cotton cloth soaked in Liquor, the film surface showed no signs of peeling or scratches.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and are made use of as lasing products to generate ultrashort (~ 100-two hundred fs) high electric power pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact get more info laser techniques.
Spatial structure of your beam and also the corresponding depth profiles I on the output on the laser.
