Employing our advertising bundle, you can Screen your brand, further under your product or service description, and these will been noticed by several photonics pros.
This special characteristic of ultrafast pulses allows nonlinear optical interaction with tissue at small Total exposure, and drives apps like deep-tissue multiphoton microscopy and significant-precision eye medical procedures
We current a dual-crystal Yb:KGW laserthat iscapable to operate for a Q-switched oscillator with output ability as many as 24 W and pulse size of 20 ns,or as a regenerative amplifier with output electric power up to 21 W and pulse period below two hundred fs soon after compression of chirped pulses. Each lasers have superb beam high-quality with beam parameter M2
Coloration-coded reflectivity of the Bragg mirror as being a perform of wavelength and angle in the incident beam.
By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW mainly because of the similar dimensions of such chemical features nearly a hundred% of Yb-doping may very well be reached. This one of a kind characteristic permits ytterbium to take the position of yttrium with almost no disruption for the crystal’s lattice.
The monoclinic crystal constructions results in a purely natural birefringence, helping to avoid thermally induced polarization rotation and depolarization decline.

Even so, as soon as Nd3+:YAG became commercially obtainable, the curiosity in CaWO4 dropped sharply. In later on several years, selected other tungstate crystals began to catch the attention of a lot of attention.
While ytterbium-doped laser acquire media generally show a small quantum defect, ytterbium-doped tungstates enable for especially little values. For example, a 1030-nm Yb:YAG laser would Ordinarily be pumped all over 940 nm, While Yb:KGW or Yb:KYW could be most competently pumped all around 981 nm.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared to its counterpart Yb:KGW, is actually a exceptional material that performs a crucial role in laser technology. Its Key perform should be to make ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
Request RP Photonics for virtually any suggestions about tungstate lasers, such as femtosecond lasers and significant-energy lasers.
