The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is quite huge in comparison with that of Yb:YAG. This enables for extensive wavelength tunability and for Substantially shorter pulse durations from method-locked lasers. Values effectively beneath 100 fs happen to be achieved with passive manner locking.
This special characteristic of ultrafast pulses allows nonlinear optical interaction with tissue at lower Over-all publicity, and drives apps which include deep-tissue multiphoton microscopy and superior-precision eye surgery
time. Crystals with the compound melts congruently at 1007 oC, on the other hand melt crystallization of top of the range crystal is unattainable as a consequence of period changeover at ~920 oC. The very best seeded solution strategy from
The absorption and emission spectra of Yb:KYW Crystals Exhibit powerful peaks at 980 nm and 1030 nm, respectively, guaranteeing economical Power conversion and significant effectiveness in laser units.
Optical layout of a laser with direct pumping Using the radiation of semiconductor injection lasers. LD is definitely an IPG Photonics laser diode with fiber output in the radiation, WP is actually a fifty percent-wave plate, CL is really a collimating lens, FL is really a concentrating lens, AE can be an Lively aspect made out of an Yb:KYW crystal, DM is actually a spherical dichroic mirror, M1-M6 are definitely the cavity mirrors, OC will be the output mirror, and SAM can be a semiconductor saturable-absorber mirror.
Adhesion Exam Compliant with MIL-C-675C armed service specifications, an adhesion take a look at included applying a tape that meets LT-ninety requirements onto the lens movie layer. The tape was affixed absolutely then eradicated vertically. This procedure was performed three times, causing no blistering or peeling.
Raman, luminescence and transmission spectra reveal optical attributes owing into the presence of thulium ions, and therefore the products may be additional examined inside the scope of laser and luminescence purposes.
A substantial brightnessQ-switched oscillator and regenerative amplifier according to a twin-crystal Yb:KGW laser
For tungstates, the ytterbium doping concentration can be very superior devoid of important quenching because the changed ions have an extremely similar ion radius, as well as inter-ion distance is website relatively substantial.
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW due to the identical dimensions of those chemical factors as much as a hundred% of Yb-doping may very well be reached.
The thermal conductivity of widespread double tungstates is in the order to three–4 W/(K m) �?which isn't terrible in comparison with other laser crystals (Even though several periods below for YAG), and pretty significant in comparison Together with the thermal conductivity of regular Eyeglasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, is a remarkable product that performs a crucial part in laser technologies. Its primary functionality will be to create ultrashort pulses of sunshine, spanning just some hundred femtoseconds.
Talk to RP Photonics for almost any guidance about tungstate lasers, which includes femtosecond lasers and high-electricity lasers.
