The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison to its counterpart Yb:KGW, can be a extraordinary materials that plays a significant purpose in laser technologies. Its Principal purpose is always to generate ultrashort pulses of light, spanning only a few hundred femtoseconds.
time. Crystals of the compound melts congruently at 1007 oC, however soften crystallization of top of the range crystal is unattainable on account of period transition at ~920 oC. The top seeded Alternative method from
Color-coded reflectivity of the Bragg mirror as being a functionality of wavelength and angle with the incident beam.
Optical format of a laser with direct pumping Together with the radiation of semiconductor injection lasers. LD is really an IPG Photonics laser diode with fiber output of your radiation, WP is actually a 50 percent-wave plate, CL can be a collimating lens, FL is often a concentrating lens, AE is really an Energetic factor made out of an Yb:KYW crystal, DM can be a spherical dichroic mirror, M1-M6 tend to be the cavity mirrors, OC could be the output mirror, and SAM can be a semiconductor saturable-absorber mirror.
The monoclinic crystal buildings ends in a pure birefringence, assisting to stay clear of thermally induced polarization rotation and depolarization decline.
Raman, luminescence and transmission spectra expose optical characteristics owing towards the existence of thulium ions, and so the materials could be even further examined while in the scope of laser and luminescence applications.
A superior brightnessQ-switched oscillator and regenerative amplifier determined by a twin-crystal Yb:KGW laser
EKSMA Optics employs cookies to supply you with the ideal browsing practical experience. In the event you continue on to implement our products and services, We are going to believe that you just comply with the use of such cookies.
By substituting get more info yttrium with ytterbium inside the crystal lattice of Yb:KYW mainly because of the related sizes of such chemical factors up to one hundred% of Yb-doping can be attained.
The thermal conductivity of widespread double tungstates is from the buy to three–4 W/(K m) �?which is not negative compared with other laser crystals (although a number of times under for YAG), and fairly large as opposed Along with the thermal conductivity of common glasses.
Li2WO4-WO3 flux was productively utilized cutting down The expansion temperature down below 900 oC. According to one crystal x-ray measurements, the crystal corresponds to the P2/n space team.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)two) crystal at space temperature were being measured. The emission spectrum and life time from the three F four psyched point out have been determined. Applying conventional and modified Judd–Ofelt theories, the depth parameters along with the radiative lifetimes were calculated and very good agreement Together with the experimental outcomes was attained for each theories.
In this article you could submit concerns and responses. In terms of they get approved by the writer, they may seem over this paragraph together with the writer’s reply. The writer will decide on acceptance based upon particular conditions. Essentially, the issue has to be of sufficiently wide curiosity.
