The get bandwidth e.g. of Yb:KGW and Yb:KYW is rather big when compared with that of Yb:YAG. This permits for vast wavelength tunability and for A lot shorter pulse durations from method-locked lasers. Values well beneath 100 fs are realized with passive mode locking.
The comparison with glasses is appropriate For the reason that substantial get bandwidth makes it possible for e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
time. Crystals from the compound melts congruently at 1007 oC, having said that melt crystallization of top of the range crystal is not possible due to phase changeover at ~920 oC. The top seeded Option technique from
FIG. four. Autocorrelation functionality of the pulse 共a兲and spectrum 共b兲of a laser with an oblong Lively element for an output electricity of 700 mW. The width of
This paper describes a femtosecond laser regenerative amplifier based on two Yb:KYW crystals with direct longitudinal pumping by strong linear arrays of semiconductor injection lasers having fiber output. To forestall spectral narrowing throughout amplification as well as the corresponding lengthening of the amplified pulse when it truly is compressed, a mix of two Yb:KYW crystals ended up utilized, with the spectral maxima with the amplification shifted relative to each other and with spectral profiling with the amplified radiation.
Adhesion Exam Compliant with MIL-C-675C navy requirements, an adhesion test concerned applying a tape that meets LT-ninety specs on to the lens film layer. The tape was affixed totally then removed vertically. This process was performed thrice, resulting in no blistering or peeling.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and they are employed as lasing components to generate ultrashort (~ one hundred-two hundred fs) substantial energy pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes operating at 981 nm supports compact laser methods.
A superior brightnessQ-switched oscillator and regenerative amplifier dependant on a twin-crystal Yb:KGW laser

... Not only the place of crystal within the cavity but additionally the amplification axis of crystal impacts the laser check here operation tremendously, because the absorption and emission cross sections from the crystal are really different in accordance with the orientation with the crystal.
The thermal conductivity of popular double tungstates is on the purchase to three–4 W/(K m) �?which isn't terrible in comparison with other laser crystals (Despite the fact that numerous situations below for YAG), and relatively significant as opposed While using the thermal conductivity of common Eyeglasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared with its counterpart Yb:KGW, is really a exceptional product that plays a vital part in laser know-how. Its Key purpose is always to produce ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
At the same time, a shorter laser wavelength can be attained; it is achievable to function using a quantum defect well down below 1%. To be a consequence, the heat technology can be so compact that this partly compensates the lower thermal conductivity.
