In useful phrases, the Yb:KYW crystal has uncovered its niche in large-electricity laser apps as a consequence of its power to generate high Vitality ultrashort laser pulses even though keeping a compact dimension. The interplay of its attributes �?seamless ytterbium substitution, powerful absorption traits, ultrashort pulse technology and effectiveness in Vitality conversion �?positions the Yb:KYW crystal like a cornerstone within the laser technologies, masking various fields starting from scientific exploration to industrial programs.
This distinctive attribute of ultrafast pulses enables nonlinear optical conversation with tissue at lower overall publicity, and drives apps for instance deep-tissue multiphoton microscopy and higher-precision eye surgical treatment
time. Crystals of the compound melts congruently at 1007 oC, on the other hand melt crystallization of top quality crystal is impossible on account of section transition at ~920 oC. The very best seeded solution system from

This paper describes a femtosecond laser regenerative amplifier depending on two Yb:KYW crystals with direct longitudinal pumping by impressive linear arrays of semiconductor injection lasers having fiber output. To prevent spectral narrowing throughout amplification and also the corresponding lengthening of the amplified pulse when it is compressed, a mix of two Yb:KYW crystals have been employed, Using the spectral maxima of the amplification shifted relative to one another and with spectral profiling of the amplified radiation.
Ahead of the event of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser achieve medium. It was in truth Utilized in the first continually functioning crystal laser.

High-electricity repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical applications
When ytterbium-doped laser get media generally show a little quantum defect, ytterbium-doped tungstates enable for specifically modest values. One example is, a 1030-nm Yb:YAG laser would Ordinarily be pumped all around 940 nm, whereas Yb:KGW or Yb:KYW could be most efficiently pumped all-around 981 nm.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison with its counterpart Yb:KGW, is really a outstanding product that performs a significant purpose in laser know-how. Its primary function would be to deliver ultrashort pulses of light, spanning just a couple hundred femtoseconds.
Question RP Photonics for any assistance regarding tungstate lasers, including femtosecond lasers and significant-electric power lasers.
