The obtain bandwidth e.g. of Yb:KGW and Yb:KYW is rather significant in comparison with that of Yb:YAG. This permits for vast wavelength tunability and for Considerably shorter pulse durations from manner-locked lasers. Values effectively under 100 fs happen to be achieved with passive mode locking.
The comparison with glasses is appropriate since the significant attain bandwidth enables e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
We present a twin-crystal Yb:KGW laserthat iscapable to operate as being a Q-switched oscillator with output electric power nearly 24 W and pulse duration of 20 ns,or like a regenerative amplifier with output ability as many as 21 W and pulse period beneath 200 fs just after compression of chirped pulses. Both of those lasers have great beam high quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Screen solid peaks at 980 nm and 1030 nm, respectively, guaranteeing effective Power conversion and substantial efficiency in laser methods.
By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW as a result of comparable measurements of such chemical factors as many as one hundred% of Yb-doping could be accomplished. This distinctive characteristic permits ytterbium to go ahead and take position of yttrium with practically no disruption on the crystal’s lattice.
Just after air drying and subsequent cleaning that has a cotton cloth soaked in Liquor, the movie floor showed no signs of peeling or scratches.
FIG. one. Optical structure of the laser with immediate pumping With all the radiation of semiconductor injection lasers. LD can be an IPG Photonics laser diode with fiber output
Tungstates are inclined to have significant Raman coefficients (�?Raman scattering). Hence, they will produce substantial Raman gain at moderate optical intensities. It is achievable to utilize the laser crystal alone like a Raman converter.
EKSMA Optics makes use of cookies to supply you with the best shopping encounter. For those who go on to implement our providers, We'll suppose that you just conform to the usage of this sort of more info cookies.
By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW mainly because of the equivalent sizes of these chemical components approximately a hundred% of Yb-doping can be reached.
