KYW Crystal - An Overview
Blog Article
In functional phrases, the Yb:KYW crystal has located its area of interest in superior-power laser purposes due to its ability to deliver superior Electricity ultrashort laser pulses when keeping a compact size. The interaction of its capabilities �?seamless ytterbium substitution, sturdy absorption qualities, ultrashort pulse technology and effectiveness in Vitality conversion �?positions the Yb:KYW crystal as a cornerstone from the laser know-how, covering varied fields starting from scientific investigation to industrial apps.
The comparison with Eyeglasses is suitable Because the significant attain bandwidth lets e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
We present a dual-crystal Yb:KGW laserthat iscapable to operate like a Q-switched oscillator with output electricity as much as 24 W and pulse size of twenty ns,or being a regenerative amplifier with output power approximately 21 W and pulse length below 200 fs soon after compression of chirped pulses. Both of those lasers have exceptional beam excellent with beam parameter M2
Color-coded reflectivity of a Bragg mirror being a functionality of wavelength and angle of the incident beam.
Optical structure of a laser with immediate pumping Along with the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output in the radiation, WP is really a 50 percent-wave plate, CL is really a collimating lens, FL is usually a focusing lens, AE is really an active factor comprised of an Yb:KYW crystal, DM is actually a spherical dichroic mirror, M1-M6 are definitely the cavity mirrors, OC may be the output mirror, and SAM is often a semiconductor saturable-absorber mirror.
The monoclinic crystal constructions leads to a all-natural birefringence, helping to stay clear of thermally induced polarization rotation and depolarization decline.
Raman, luminescence and transmission spectra expose optical attributes owing for the presence of thulium ions, and so the resources may very well be further more examined from the scope of laser and luminescence apps.
A significant brightnessQ-switched oscillator and regenerative amplifier based upon a twin-crystal Yb:KGW laser

Higher-electricity repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical apps
Due to Earlier detected malicious habits which originated in the community you might be working with, make sure you ask for unblock to website.
This tandem of characteristics has considerably-reaching implications, check here specifically in the development of compact still powerfull lasers.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at place temperature were measured. The emission spectrum and lifetime on the three File four excited state have been decided. Applying standard and modified Judd–Ofelt theories, the intensity parameters and also the radiative lifetimes had been calculated and excellent arrangement Together with the experimental benefits was received for equally theories.
In this article it is possible to post queries and opinions. As far as they get acknowledged via the author, they're going to surface over this paragraph along with the writer’s respond to. The author will choose acceptance depending on selected conditions. Essentially, the issue should be of sufficiently broad interest.
