The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is rather big compared with that of Yb:YAG. This permits for extensive wavelength tunability and for A lot shorter pulse durations from method-locked lasers. Values very well under a hundred fs have been achieved with passive mode locking.
This distinctive characteristic of ultrafast pulses allows nonlinear optical conversation with tissue at minimal overall publicity, and drives applications which include deep-tissue multiphoton microscopy and substantial-precision eye surgical treatment
We current a twin-crystal Yb:KGW laserthat iscapable to function for a Q-switched oscillator with output ability up to 24 W and pulse duration of twenty ns,or for a regenerative amplifier with output power up to 21 W and pulse length beneath two hundred fs just after compression of chirped pulses. Both of those lasers have great beam excellent with beam parameter M2
Coloration-coded reflectivity of the Bragg mirror as a perform of wavelength and angle in the incident beam.
This paper describes a femtosecond laser regenerative amplifier dependant on two Yb:KYW crystals with immediate longitudinal pumping by strong linear arrays of semiconductor injection lasers obtaining fiber output. To avoid spectral narrowing in the course of amplification and also the corresponding lengthening of the amplified pulse when it is actually compressed, a combination of two Yb:KYW crystals were applied, Together with the spectral maxima from the amplification shifted relative to one another and with spectral profiling from the amplified radiation.
In advance of the development of Nd:YAG, Nd3+:CaWO4 was an important exceptional-earth-doped laser acquire medium. It had been in actual fact used in the initial consistently operating crystal laser.
Raman, luminescence and transmission spectra expose optical attributes owing for the presence of thulium ions, and so the elements may very well be further more examined during the scope of laser and luminescence purposes.
A superior brightnessQ-switched oscillator and regenerative amplifier dependant on a twin-crystal Yb:KGW laser
For tungstates, click here the ytterbium doping focus can be very substantial without important quenching as the changed ions have an extremely very similar ion radius, and the inter-ion distance is pretty huge.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW because of the similar dimensions of those chemical components nearly 100% of Yb-doping could be realized.
The thermal conductivity of widespread double tungstates is from the get to 3–four W/(K m) �?which is not terrible in contrast with other laser crystals (Whilst numerous situations under for YAG), and quite big when compared Using the thermal conductivity of usual glasses.
Li2WO4-WO3 flux was properly utilized reducing the growth temperature under 900 oC. As outlined by one crystal x-ray measurements, the crystal corresponds to the P2/n Area group.
