The 5-Second Trick For KYW Crystal

The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is quite substantial compared with that of Yb:YAG. This allows for extensive wavelength tunability and for A great deal shorter pulse durations from mode-locked lasers. Values nicely under one hundred fs are obtained with passive manner locking.

We current a dual-crystal Yb:KGW laserthat iscapable to function like a Q-switched oscillator with output electricity approximately 24 W and pulse duration of 20 ns,or like a regenerative amplifier with output power as much as 21 W and pulse duration under 200 fs right after compression of chirped pulses. Both of those lasers have exceptional beam high-quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals display sturdy peaks at 980 nm and 1030 nm, respectively, guaranteeing successful Strength conversion and substantial effectiveness in laser devices.
Optical format of the laser with immediate pumping With all the radiation of semiconductor injection lasers. LD can be an IPG Photonics laser diode with fiber output in the radiation, WP is actually a 50 percent-wave plate, CL is usually a collimating lens, FL is really a focusing lens, AE is undoubtedly an Energetic ingredient made from an Yb:KYW crystal, DM is really a spherical dichroic mirror, M1-M6 are classified as the cavity mirrors, OC could be the output mirror, and SAM is often a semiconductor saturable-absorber mirror.
Adhesion Take a look at Compliant with MIL-C-675C military requirements, an adhesion exam involved applying a tape that satisfies LT-90 specifications onto the lens film layer. The tape was affixed totally after which taken out vertically. This treatment was done 3 times, resulting in no blistering or peeling.

Higher-electricity repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical purposes
The thermal conductivity of frequent double tungstates is with the order to 3–four W/(K m) �?which isn't undesirable in contrast with other laser crystals (While various occasions below for YAG), and quite big in comparison While using the thermal conductivity of typical glasses.
Li2WO4-WO3 flux was productively utilized lessening The expansion temperature down below 900 oC. Based on single crystal x-ray measurements, the crystal corresponds towards the P2/n Area group.
