Using our promotion package deal, you can Show your symbol, even more underneath your product or service description, and these will been viewed by many photonics industry experts.
This exceptional characteristic of ultrafast pulses enables nonlinear optical interaction with tissue at reduced All round exposure, and drives applications for instance deep-tissue multiphoton microscopy and higher-precision eye surgical procedure
Femtosecond laser depending on Yb:KYW crystals with suppression of spectral narrowing in the regenerative amplifier by spectral profiling of the pulse
The absorption and emission spectra of Yb:KYW Crystals Show robust peaks at 980 nm and 1030 nm, respectively, guaranteeing effective Electricity conversion and superior effectiveness in laser units.
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW as a result of similar sizes of these chemical features up to 100% of Yb-doping might be attained. This distinctive characteristic permits ytterbium to take the location of yttrium with nearly no disruption to the crystal’s lattice.
Ahead of the development of Nd:YAG, Nd3+:CaWO4 was an important unusual-earth-doped laser get medium. It absolutely was in more info truth used in the first constantly functioning crystal laser.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and they are utilised as lasing elements to produce ultrashort (~ 100-200 fs) higher electricity pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser programs.
A significant brightnessQ-switched oscillator and regenerative amplifier according to a twin-crystal Yb:KGW laser
EKSMA Optics employs cookies to give you the very best procuring experience. Should you go on to make use of our companies, we will presume that you just agree to the usage of this kind of cookies.
... Not merely the situation of crystal inside the cavity but in addition the amplification axis of crystal influences the laser Procedure tremendously, since the absorption and emission cross sections on the crystal are quite diverse in accordance with the orientation of the crystal.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared with its counterpart Yb:KGW, is a exceptional substance that performs a vital job in laser technologies. Its Major purpose should be to deliver ultrashort pulses of sunshine, spanning just some hundred femtoseconds.
Ask RP Photonics for almost any guidance about tungstate lasers, such as femtosecond lasers and substantial-power lasers.
