In practical phrases, the Yb:KYW crystal has discovered its market in large-electrical power laser programs due to its capacity to generate higher Electrical power ultrashort laser pulses when retaining a compact sizing. The interplay of its options �?seamless ytterbium substitution, sturdy absorption characteristics, ultrashort pulse era and efficiency in Electrical power conversion �?positions the Yb:KYW crystal as being a cornerstone within the laser technologies, covering diverse fields starting from scientific exploration to industrial apps.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, can be a outstanding materials that plays a vital role in laser technological innovation. Its Most important perform would be to generate ultrashort pulses of light, spanning just a couple hundred femtoseconds.
We present a dual-crystal Yb:KGW laserthat iscapable to operate like a Q-switched oscillator with output energy as many as 24 W and pulse length of 20 ns,or for a regenerative amplifier with output electricity as many as 21 W and pulse length under two hundred fs following compression of chirped pulses. Both equally lasers have superb beam high quality with beam parameter M2
FIG. four. Autocorrelation operate of the heartbeat 共a兲and spectrum 共b兲of a laser with a rectangular Energetic ingredient for an output electric power of seven hundred mW. The width of
Optical layout of a laser with immediate pumping Together with the radiation of semiconductor injection lasers. LD is surely an IPG Photonics laser diode with fiber output from the radiation, WP can be a 50 %-wave plate, CL is usually a collimating lens, FL is really a focusing lens, AE is undoubtedly an Lively aspect created from an Yb:KYW crystal, DM is really a spherical dichroic mirror, M1-M6 are definitely the cavity mirrors, OC is the output mirror, and SAM is usually a semiconductor saturable-absorber mirror.
Adhesion Exam Compliant with MIL-C-675C military services standards, an adhesion exam involved applying a tape that fulfills LT-90 specifications on to click here the lens film layer. The tape was affixed fully after which you can eliminated vertically. This process was performed 3 times, causing no blistering or peeling.
