The obtain bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly significant in comparison with that of Yb:YAG. This allows for large wavelength tunability and for A lot shorter pulse durations from manner-locked lasers. Values properly underneath one hundred fs happen to be obtained with passive method locking.
This one of a kind attribute of ultrafast pulses permits nonlinear optical conversation with tissue at minimal overall exposure, and drives applications for instance deep-tissue multiphoton microscopy and large-precision eye surgery
We present a dual-crystal Yb:KGW laserthat iscapable to operate as being a Q-switched oscillator with output electrical power around 24 W and pulse size of 20 ns,or as being a regenerative amplifier with output electrical power around 21 W and pulse length under 200 fs after compression of chirped pulses. Each lasers have superb beam quality with beam parameter M2
Color-coded reflectivity of a Bragg mirror as being a operate of wavelength and angle on the incident beam.
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW due to similar sizes of these chemical factors approximately one hundred% of Yb-doping may be realized. This exceptional attribute permits ytterbium to take the put of yttrium with virtually no disruption into the crystal’s lattice.
Adhesion Take a look at Compliant with MIL-C-675C armed service criteria, an adhesion take a look at concerned applying a tape that satisfies LT-90 specifications on to the lens film layer. The tape was affixed totally and then taken off vertically. This treatment was performed thrice, resulting in no blistering or peeling.
Raman, luminescence and transmission spectra expose optical capabilities owing to your existence of thulium ions, and for that reason the resources may be even more researched while in the scope of laser and luminescence apps.
Spatial structure of your beam as well as corresponding depth profiles I with the output in the laser.
For tungstates, the ytterbium doping concentration can be extremely large without the need of important quenching since the changed ions have a really identical ion radius, and also the inter-ion distance is fairly significant.
Large-power repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical applications
The thermal conductivity of prevalent double tungstates is of more info the purchase to 3–4 W/(K m) �?which isn't poor as opposed with other laser crystals (Despite the fact that quite a few moments lower than for YAG), and rather huge as opposed With all the thermal conductivity of usual glasses.
Li2WO4-WO3 flux was correctly applied decreasing The expansion temperature down below 900 oC. In accordance with solitary crystal x-ray measurements, the crystal corresponds to your P2/n House team.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at area temperature were being measured. The emission spectrum and life span from the 3 F 4 thrilled state were being determined. Utilizing normal and modified Judd–Ofelt theories, the intensity parameters and also the radiative lifetimes had been calculated and great agreement with the experimental results was attained for both equally theories.
Right here you may post concerns and responses. In terms of they get recognized from the author, they're going to show up above this paragraph along with the creator’s answer. The author will decide on acceptance according to specific requirements. In essence, The problem has to be of sufficiently broad interest.
