Considerations To Know About KYW Crystal
In sensible terms, the Yb:KYW crystal has uncovered its specialized niche in superior-ability laser apps on account of its capability to produce higher energy ultrashort laser pulses though retaining a compact dimensions. The interplay of its attributes �?seamless ytterbium substitution, strong absorption features, ultrashort pulse era and effectiveness in Strength conversion �?positions the Yb:KYW crystal like a cornerstone within the laser technological know-how, covering numerous fields ranging from scientific investigate to industrial programs.The comparison with Eyeglasses is acceptable since the big achieve bandwidth lets e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
time. Crystals with the compound melts congruently at 1007 oC, having said that melt crystallization of top quality crystal is impossible on account of stage changeover at ~920 oC. The very best seeded solution strategy from
The absorption and emission spectra of Yb:KYW Crystals Show potent peaks at 980 nm and 1030 nm, respectively, guaranteeing successful Electricity conversion and significant general performance in laser units.
This paper describes a femtosecond laser regenerative amplifier determined by two Yb:KYW crystals with direct longitudinal pumping by strong linear arrays of semiconductor injection lasers possessing fiber output. To prevent spectral narrowing through amplification as well as the corresponding lengthening of the amplified pulse when it truly is compressed, a mix of two Yb:KYW crystals have been used, Together with the spectral maxima of the amplification shifted relative to one another and with spectral profiling of your amplified radiation.
The monoclinic crystal buildings brings about a natural birefringence, helping to steer clear of thermally induced polarization rotation and depolarization loss.

A high brightnessQ-switched oscillator and regenerative amplifier based on a twin-crystal Yb:KGW laser
... at 50 %-height were generated inside of a master oscillator with selfsynchronization in the axial modes, described in our previously posting. 21 The new version with the laser, unlike that described within our before article, employed an Yb:KYW crystal using an N pcut (optical axis N p in the index ellipsoid was parallel into the propagation path on the laser radiation), Along with the polarization of the generated radiation directed alongside the N m axis.
... Don't just the position of crystal in the cavity but also more info the amplification axis of crystal affects the laser operation greatly, because the absorption and emission cross sections with the crystal are really distinctive according to the orientation on the crystal.
Though ytterbium-doped laser gain media normally show a small quantum defect, ytterbium-doped tungstates permit for significantly compact values. Such as, a 1030-nm Yb:YAG laser would Generally be pumped all over 940 nm, While Yb:KGW or Yb:KYW might be most successfully pumped all around 981 nm.
Li2WO4-WO3 flux was successfully applied reducing the growth temperature down below 900 oC. Based on single crystal x-ray measurements, the crystal corresponds towards the P2/n space team.
