This unique characteristic of ultrafast pulses allows nonlinear optical conversation with tissue at very low overall exposure, and drives purposes like deep-tissue multiphoton microscopy and high-precision eye surgical procedures
The Yb:KYW crystal’s proficiency in light-weight absorption at all around 981 nm would make the crystal like minded for diode pumping. It is more Increased by its exceptional effectiveness in this method, coupled with its low quantum defect.
For anyone who is trying to accessibility This great site using an nameless Non-public/Proxy network, remember to disable that and take a look at accessing web page all over again.
Ultrafast lasers, with pulse widths of a few picoseconds (ten−twelve s) or considerably less, empower some time resolution essential in laser-enthusiastic fluorescence life span spectroscopy and imaging approaches.Additionally, they provide large pulse peak powers at higher repetition costs and reasonable normal output powers.
The monoclinic crystal structures leads to a natural birefringence, helping to stay clear of thermally induced polarization rotation and depolarization decline.
Raman, luminescence and transmission spectra expose optical features owing towards the existence of thulium ions, and for that reason the supplies could be even further analyzed from the scope of laser and luminescence applications.
Tungstates have a tendency to own significant Raman coefficients (�?Raman scattering). Therefore, they're able to make major Raman get at average optical intensities. It can be done to utilize the laser crystal by itself for a Raman converter.
... at half-top ended up generated in a learn oscillator with selfsynchronization with the axial modes, described inside our previously write-up. 21 The new edition with the laser, as opposed to that explained within our before posting, utilised an Yb:KYW crystal with the N pcut (optical axis N p of your index ellipsoid was parallel on the propagation direction with the laser radiation), With all click here the polarization of your generated radiation directed alongside the N m axis.
High-electric power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical programs
The thermal conductivity of typical double tungstates is on the order to three–4 W/(K m) �?which is not bad when compared with other laser crystals (Though quite a few instances less than for YAG), and relatively significant in comparison While using the thermal conductivity of common Eyeglasses.
There aren't any things as part of your cart. Increase items for your cart and ask for an official estimate or purchase on the internet Subtotal
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, is actually a exceptional content that plays an essential role in laser technologies. Its Main function should be to crank out ultrashort pulses of light, spanning just some hundred femtoseconds.
