The gain bandwidth e.g. of Yb:KGW and Yb:KYW is extremely significant in comparison with that of Yb:YAG. This permits for vast wavelength tunability and for A lot shorter pulse durations from method-locked lasers. Values well under a hundred fs have already been attained with passive manner locking.
This one of a kind characteristic of ultrafast pulses allows nonlinear optical interaction with tissue at small Total exposure, and drives programs which include deep-tissue multiphoton microscopy and substantial-precision eye surgical procedures
The Yb:KYW crystal’s proficiency in gentle absorption at all-around 981 nm can make the crystal well suited for diode pumping. It truly is more enhanced by its extraordinary effectiveness in this process, coupled with its reduced quantum defect.
The absorption and emission spectra of Yb:KYW Crystals Screen powerful peaks at 980 nm and 1030 nm, respectively, making sure successful energy conversion and substantial performance in laser techniques.
Optical layout of the laser with immediate pumping With all the radiation of semiconductor injection lasers. LD is an IPG Photonics laser diode with fiber output of the radiation, WP can be a 50 percent-wave plate, CL is often a collimating lens, FL is usually a concentrating lens, AE is really an active factor created from an Yb:KYW crystal, DM is often a spherical dichroic mirror, M1-M6 would be the cavity mirrors, OC will be the output mirror, and SAM is often a semiconductor saturable-absorber mirror.
After air drying and subsequent cleansing which has a cotton cloth soaked in Alcoholic beverages, the film surface area showed no signs of peeling or scratches.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and are utilized as lasing components to create ultrashort (~ a hundred-200 fs) large ability pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes running at 981 nm supports compact laser devices.
A significant brightnessQ-switched oscillator and regenerative amplifier depending on a dual-crystal Yb:KGW laser
