The acquire bandwidth e.g. of Yb:KGW and Yb:KYW may be very substantial in contrast with that of Yb:YAG. This permits for wide wavelength tunability and for Considerably shorter pulse durations from manner-locked lasers. Values nicely beneath 100 fs have already been achieved with passive mode locking.
The comparison with Eyeglasses is acceptable For the reason that huge attain bandwidth permits e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
We present a dual-crystal Yb:KGW laserthat iscapable to operate like a Q-switched oscillator with output electric power up to 24 W and pulse length of 20 ns,or like a regenerative amplifier with output energy up to 21 W and pulse period under 200 fs just after compression of chirped pulses. Both lasers have excellent beam high-quality with beam parameter M2
FIG. four. Autocorrelation perform of the pulse 共a兲and spectrum 共b兲of a laser with a rectangular Energetic ingredient for an output power of 700 mW. The width of
This paper describes a femtosecond laser regenerative amplifier dependant on two Yb:KYW crystals with direct longitudinal pumping by highly effective linear arrays of semiconductor injection lasers having fiber output. To circumvent spectral narrowing through amplification along with the corresponding lengthening of the amplified pulse when it can be compressed, a mix of two Yb:KYW crystals were being employed, Along with the spectral maxima of the amplification shifted relative to each other and with spectral profiling from the amplified radiation.
Before the event of Nd:YAG, Nd3+:CaWO4 was a very important rare-earth-doped laser get medium. It absolutely was in actual fact used in the very first constantly working crystal laser.
Raman, luminescence and transmission spectra reveal optical characteristics owing to your existence of thulium ions, and as a consequence the resources might be further more examined inside the scope of laser and luminescence applications.
5 mm in addition to the center of your beam caustic. In order to Test the method matching simulation, we carried out the experiment with Ng-Slash crystal oscillator, which was formulated Earlier and in a similar issue with simulation [11]. As demonstrated in Determine 3(b) with pink dots and line, the CW output ability is highly dependent on the situation of laser crystal and the experimental result coincides perfectly with simulation outcome. Being a note, multimode operation occurred in experiment in the event the sizing from the pump beam is larger sized than TEM00 cavity method and it leads to bigger CW output power in the displacement location underneath three.five mm.

By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW as a result of identical sizes of those chemical aspects up to a hundred% of Yb-doping could possibly be achieved.

Simultaneously, a shorter laser wavelength could be obtained; it is feasible to function which has a quantum defect perfectly click here below 1%. As a consequence, the warmth era can be so little that this partly compensates the reduce thermal conductivity.
