In sensible phrases, the Yb:KYW crystal has discovered its market in superior-electric power laser applications on account of its capacity to generate higher Electricity ultrashort laser pulses though protecting a compact dimension. The interaction of its features �?seamless ytterbium substitution, solid absorption qualities, ultrashort pulse technology and efficiency in Strength conversion �?positions the Yb:KYW crystal like a cornerstone within the laser technologies, masking assorted fields ranging from scientific research to industrial applications.

The comparison with glasses is appropriate Considering that the significant acquire bandwidth allows e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.

We current a twin-crystal Yb:KGW laserthat iscapable to work being a Q-switched oscillator with output electrical power as much as 24 W and pulse size of twenty ns,or as a regenerative amplifier with output electric power nearly 21 W and pulse length beneath 200 fs following compression of chirped pulses. Each lasers have exceptional beam quality with beam parameter M2

Ultrafast lasers, with pulse widths of a few picoseconds (ten−12 s) or a lot less, empower enough time resolution necessary in laser-energized fluorescence life time spectroscopy and imaging procedures.In addition, they produce large pulse peak powers at large repetition fees and reasonable average output powers.

The monoclinic crystal structures brings about a organic birefringence, assisting to stay clear of thermally induced polarization rotation and depolarization decline.

... Not simply the position of crystal from the cavity but additionally the amplification axis of crystal influences the laser operation drastically, since the absorption and emission cross sections with the crystal are rather distinct based on the orientation with the crystal.

While ytterbium-doped laser obtain media frequently show a little quantum defect, ytterbium-doped tungstates allow for particularly tiny values. For example, a 1030-nm Yb:YAG laser would normally be pumped about 940 nm, whereas Yb:KGW or Yb:KYW might be most proficiently pumped all-around 981 nm.

Li2WO4-WO3 flux was productively applied minimizing The expansion temperature beneath 900 oC. In line with single crystal x-ray measurements, the crystal corresponds to your P2/n space group.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison with its counterpart Yb:KGW, can be a impressive substance that performs an important part in laser technology. Its Key purpose will be to deliver ultrashort pulses of light, spanning just a couple hundred femtoseconds.

Inquire RP Photonics for any assistance concerning tungstate lasers, together with femtosecond lasers and substantial-electrical power lasers.
