In useful conditions, the Yb:KYW crystal has observed its area of interest in superior-energy laser apps on account of its power to create large energy ultrashort laser pulses though preserving a compact dimension. The interaction of its capabilities �?seamless ytterbium substitution, strong absorption features, ultrashort pulse era and effectiveness in Strength conversion �?positions the Yb:KYW crystal being a cornerstone within the laser engineering, covering numerous fields ranging from scientific investigation to industrial applications.
The comparison with Eyeglasses is acceptable For the reason that significant obtain bandwidth enables e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
We present a twin-crystal Yb:KGW laserthat iscapable to operate for a Q-switched oscillator with output power approximately 24 W and pulse length of 20 ns,or as a regenerative amplifier with output ability up to 21 W and pulse length beneath 200 fs following compression of chirped pulses. The two lasers have fantastic beam high quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Show robust peaks at 980 nm and 1030 nm, respectively, making sure effective Strength conversion and large overall performance in laser systems.
Optical structure of a laser with immediate pumping With all the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output in the radiation, WP is often a half-wave plate, CL is actually a collimating lens, FL is actually a focusing lens, AE is definitely an active ingredient comprised of an Yb:KYW crystal, DM is actually a spherical dichroic mirror, M1-M6 tend to be the cavity mirrors, OC is definitely the output mirror, and SAM is usually a semiconductor saturable-absorber mirror.
Right after air drying and subsequent cleansing using a cotton cloth soaked in alcohol, the movie surface confirmed no signs of peeling or scratches.
