The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is quite significant in comparison with that of Yb:YAG. This enables for wide wavelength tunability and for much shorter pulse durations from method-locked lasers. Values effectively underneath one hundred fs happen to be reached with passive mode locking.
This unique attribute of ultrafast pulses enables nonlinear optical conversation with tissue at very low In general exposure, and drives applications which include deep-tissue multiphoton microscopy and substantial-precision eye medical procedures
The Yb:KYW crystal’s proficiency in gentle absorption at around 981 nm helps make the crystal compatible for diode pumping. It is actually additional enhanced by its impressive effectiveness in this method, coupled with its lower quantum defect.
FIG. 4. Autocorrelation purpose of the pulse 共a兲and spectrum 共b兲of the laser with an oblong active aspect for an output electric power of 700 mW. The width of
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 as well as the corresponding lengthening from the amplified pulse when it is actually compressed, a mix 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.
Adhesion Test Compliant with MIL-C-675C armed forces benchmarks, an adhesion exam included implementing a tape that satisfies LT-90 technical specs on to the lens movie layer. The tape was affixed absolutely and afterwards eliminated vertically. This technique was executed 3 times, causing no blistering or peeling.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and they are used as lasing products to produce ultrashort (~ a hundred-two hundred fs) superior energy pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser devices.
A high brightnessQ-switched oscillator and regenerative amplifier according to a twin-crystal Yb:KGW laser
... at fifty percent-height were being produced within a master oscillator with selfsynchronization of your axial modes, explained in our before short article. 21 The new version of the laser, contrary to that described inside our earlier posting, utilised an Yb:KYW crystal with the N pcut (optical axis N p of your index ellipsoid was parallel on the propagation direction on the laser radiation), Using the polarization with the generated radiation directed along the N m axis.
... Not merely the situation of crystal from the cavity but will also the amplification axis of crystal has an effect on the read more laser Procedure considerably, since the absorption and emission cross sections on the crystal are very diverse based on the orientation in the crystal.
The thermal conductivity of prevalent double tungstates is from the get to 3–four W/(K m) �?which isn't undesirable compared with other laser crystals (While a number of situations lower than for YAG), and rather big when compared with the thermal conductivity of normal Eyeglasses.
Li2WO4-WO3 flux was correctly applied lowering The expansion temperature down below 900 oC. Based on solitary crystal x-ray measurements, the crystal corresponds on the P2/n Place team.
