This distinctive attribute of ultrafast pulses allows nonlinear optical interaction with tissue at lower All round publicity, and drives programs like deep-tissue multiphoton microscopy and large-precision eye surgical treatment
We current a twin-crystal Yb:KGW laserthat iscapable to work for a Q-switched oscillator with output ability as much as 24 W and pulse size of 20 ns,or for a regenerative amplifier with output ability nearly 21 W and pulse length underneath two hundred fs soon after compression of chirped pulses. Each lasers have great beam high quality with beam parameter M2
Coloration-coded reflectivity of a Bragg mirror like a functionality of wavelength and angle of the incident beam.
Optical layout of the laser with direct pumping Using the radiation of semiconductor injection lasers. LD is an IPG Photonics laser diode with fiber output with the radiation, WP is actually a 50 %-wave plate, CL is actually a collimating lens, FL is actually a focusing lens, AE can be an Lively factor made from an Yb:KYW crystal, DM can be a spherical dichroic mirror, M1-M6 are definitely the cavity mirrors, OC would be the output mirror, and SAM is a semiconductor saturable-absorber mirror.
Adhesion Test Compliant with MIL-C-675C armed forces criteria, an adhesion exam involved applying a tape that meets LT-ninety technical specs on to the lens movie layer. The tape was affixed thoroughly after which you can taken out vertically. This treatment was performed three times, resulting in no blistering or peeling.
Raman, luminescence and transmission spectra expose optical capabilities owing into the existence of thulium ions, and therefore the supplies could possibly be even more analyzed while in the scope of laser and luminescence apps.
A substantial brightnessQ-switched oscillator and regenerative amplifier according to a dual-crystal Yb:KGW laser
EKSMA Optics works by using cookies to supply you with the greatest browsing knowledge. When you keep on to implement our solutions, We're going to believe that you just more info agree to using this sort of cookies.
Nonetheless, after Nd3+:YAG grew to become commercially readily available, the fascination in CaWO4 dropped sharply. In later on yrs, selected other tungstate crystals began to draw in many awareness.
On account of Formerly detected destructive habits which originated through the network you might be working with, you should request unblock to web page.
Li2WO4-WO3 flux was correctly applied minimizing The expansion temperature beneath 900 oC. As outlined by one crystal x-ray measurements, the crystal corresponds towards the P2/n Room team.
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, is actually a exceptional content that performs a significant purpose in laser technological know-how. Its Most important operate is usually to create ultrashort pulses of light, spanning just a couple hundred femtoseconds.
Check with RP Photonics for just about any advice relating to tungstate lasers, which includes femtosecond lasers and high-electric power lasers.
