The comparison with glasses is suitable For the reason that substantial get bandwidth lets e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
The Yb:KYW crystal’s proficiency in light absorption at about 981 nm helps make the crystal compatible for diode pumping. It is actually additional Improved by its extraordinary efficiency in this process, coupled with its minimal quantum defect.
FIG. four. Autocorrelation functionality of the heartbeat 共a兲and spectrum 共b兲of a laser with an oblong active component for an output electric power of seven-hundred mW. The width of
This paper describes a femtosecond laser regenerative amplifier according to two Yb:KYW crystals with immediate longitudinal pumping by potent linear arrays of semiconductor injection lasers having fiber output. To stop spectral narrowing throughout amplification and also the corresponding lengthening of the amplified pulse when it is actually compressed, a combination of two Yb:KYW crystals were made use of, Along with the spectral maxima in the amplification shifted relative to one another and with spectral profiling in the amplified radiation.
Just before the event of Nd:YAG, Nd3+:CaWO4 was a very important scarce-earth-doped laser obtain medium. It absolutely was in reality Employed in the very first repeatedly operating crystal laser.
Raman, luminescence and transmission spectra expose optical features owing towards the presence of thulium ions, and so the elements can be more studied while in the scope of laser and luminescence purposes.
Spatial composition of your beam as well as corresponding depth profiles I on the output in the laser.
For tungstates, the ytterbium doping concentration can be quite superior without having sizeable quenching because the replaced ions have an exceedingly comparable ion radius, as well as the inter-ion length is pretty massive.
High-electric power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical purposes
