The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is extremely big in contrast with that of Yb:YAG. This allows for wide wavelength tunability and for Substantially shorter pulse durations from method-locked lasers. Values properly under 100 fs happen to be accomplished with passive manner locking.
This can be a preview of subscription information, log in by using an establishment to examine obtain. Obtain this article
Femtosecond laser depending on Yb:KYW crystals with suppression of spectral narrowing in a regenerative amplifier by spectral profiling of the pulse
FIG. 4. Autocorrelation function of the heartbeat 共a兲and spectrum 共b兲of a laser with a rectangular Lively factor for an output power of seven hundred mW. The width of
By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW as a result of comparable sizes of these chemical things as many as 100% of Yb-doping might be obtained. This exceptional characteristic permits ytterbium to take the place of yttrium with practically no disruption for the crystal’s lattice.
Adhesion Take a look at Compliant with MIL-C-675C military services standards, an adhesion take a look at concerned applying a tape that meets LT-90 requirements on to the lens film layer. The tape was affixed totally after which you can taken out vertically. This process was performed three times, resulting in no blistering or peeling.
Raman, luminescence and transmission spectra expose optical characteristics owing for the existence of thulium ions, and so the supplies can be even further studied while in the scope of laser and luminescence purposes.

By substituting yttrium with here ytterbium in the crystal lattice of Yb:KYW due to the identical measurements of those chemical components up to a hundred% of Yb-doping may be attained.
The thermal conductivity of frequent double tungstates is of the get to 3–4 W/(K m) �?which isn't negative in contrast with other laser crystals (although various instances less than for YAG), and quite massive compared While using the thermal conductivity of normal Eyeglasses.
