Making use of our advertising and marketing deal, you'll be able to display your brand, additional below your product description, and these will been seen by lots of photonics experts.
This special characteristic of ultrafast pulses permits nonlinear optical interaction with tissue at low Total publicity, and drives purposes like deep-tissue multiphoton microscopy and substantial-precision eye operation
time. Crystals from the compound melts congruently at 1007 oC, even so soften crystallization of high quality crystal is not possible due to phase transition at ~920 oC. The best seeded Resolution process from
The absorption and emission spectra of Yb:KYW Crystals display solid peaks at 980 nm and 1030 nm, respectively, guaranteeing successful Electrical power conversion and significant general performance in laser units.
Optical layout of a laser with immediate pumping While using the radiation of semiconductor injection lasers. LD is surely an IPG Photonics laser diode with fiber output of your radiation, WP is usually a 50 percent-wave plate, CL is usually a collimating lens, FL is actually a focusing lens, AE is definitely an Lively factor constructed from an Yb:KYW crystal, DM is often a spherical dichroic mirror, M1-M6 are definitely 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 purely natural birefringence, assisting to stay clear of thermally induced polarization rotation and depolarization reduction.
Raman, luminescence and transmission spectra expose optical capabilities owing for the more info existence of thulium ions, and for that reason the products can be more studied within the scope of laser and luminescence programs.
Spatial structure of the beam and also the corresponding depth profiles I in the output with the laser.
For tungstates, the ytterbium doping concentration can be extremely higher without the need of substantial quenching as the changed ions have a really comparable ion radius, and also the inter-ion distance is relatively massive.
High-ability repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical purposes
The thermal conductivity of prevalent double tungstates is of the get to 3–four W/(K m) �?which is not lousy in comparison with other laser crystals (Even though numerous occasions lower than for YAG), and rather massive in comparison Along with the thermal conductivity of regular Eyeglasses.
Li2WO4-WO3 flux was efficiently used minimizing the growth temperature underneath 900 oC. In accordance with one crystal x-ray measurements, the crystal corresponds to the P2/n Room team.
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison with its counterpart Yb:KGW, is usually a outstanding substance that performs an essential position in laser technological innovation. Its Principal purpose will be to deliver ultrashort pulses of sunshine, spanning just some hundred femtoseconds.
Question RP Photonics for just about any guidance about tungstate lasers, which include femtosecond lasers and substantial-energy lasers.
