Utilizing our advertising and marketing package deal, you are able to display your brand, even further under your solution description, and these will been witnessed by a lot of photonics pros.
This unique characteristic of ultrafast pulses enables nonlinear optical conversation with tissue at lower General publicity, and drives programs such as deep-tissue multiphoton microscopy and significant-precision eye medical procedures
Femtosecond laser based on Yb:KYW crystals with suppression of spectral narrowing in the regenerative amplifier by spectral profiling of the heart beat
The absorption and emission spectra of Yb:KYW Crystals Screen solid peaks at 980 nm and 1030 nm, respectively, making certain productive Electricity conversion and significant general performance in laser units.
By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW due to comparable measurements of those chemical aspects nearly a hundred% of Yb-doping could be accomplished. This distinctive characteristic permits ytterbium to go ahead and take area of yttrium with just about no disruption to your crystal’s lattice.
Ahead of the event of Nd:YAG, Nd3+:CaWO4 was a very important exceptional-earth-doped laser acquire medium. It had been in actual fact used in the primary consistently functioning crystal laser.
FIG. 1. Optical format of a laser with immediate pumping with the radiation of semiconductor injection lasers. LD is really an IPG Photonics laser diode with fiber output
Tungstates tend to possess higher Raman coefficients (�?Raman scattering). As a result, they will deliver substantial Raman obtain at reasonable optical intensities. It is achievable more info to make use of the laser crystal by itself for a Raman converter.

High-electric power repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical applications
When ytterbium-doped laser achieve media frequently exhibit a little quantum defect, ytterbium-doped tungstates permit for specifically modest values. One example is, a 1030-nm Yb:YAG laser would Ordinarily be pumped all-around 940 nm, Whilst Yb:KGW or Yb:KYW may very well be most competently pumped all over 981 nm.
