Considerations To Know About KYW Crystal

The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is very massive compared with that of Yb:YAG. This permits for vast wavelength tunability and for much shorter pulse durations from method-locked lasers. Values perfectly under a hundred fs are already accomplished with passive manner locking.

This unique characteristic of ultrafast pulses permits nonlinear optical conversation with tissue at very low In general exposure, and drives applications like deep-tissue multiphoton microscopy and high-precision eye surgical procedures

The Yb:KYW crystal’s proficiency in mild absorption at around 981 nm can make the crystal like minded for diode pumping. It truly is even further enhanced by its remarkable effectiveness in this method, coupled with its small quantum defect.

Ultrafast lasers, with pulse widths of some picoseconds (ten−twelve s) or significantly less, allow enough time resolution necessary in laser-fired up fluorescence lifetime spectroscopy and imaging techniques.In addition, they deliver higher pulse peak powers at large repetition prices and moderate regular output powers.

In advance of the development of Nd:YAG, Nd3+:CaWO4 more info was an important exceptional-earth-doped laser get medium. It absolutely was in fact Employed in the very first consistently functioning crystal laser.
