We employed a transmission grating (TG) like a dispersive part within our stretcher and compressor. A compact configuration was adopted, in which the stretcher plus the compressor shared 1 grating just like that in Ref.
As well as its use like a Raman crystal, KGW can also be Employed in other optical purposes, such as in laser techniques and for a scintillator in healthcare imaging.
Its pump laser wants a short pulse period, a small time jitter, and clean temporal and spatial distributions because of the intrinsic instantaneous process. Therefore, the OPCPA procedure is more complex and pricey.
This is the preview of membership written content, log in by using an establishment to examine obtain. Entry this information
The opposite was positioned with its Np -axis parallel While using the s-polarized way. A comparison was manufactured amongst a configuration with the crystals put in the same orientation (
KGW (potassium gadolinium tungstate) is often a crystal that is often used as being a Raman crystal in Raman spectroscopy. It's really a colorless, transparent crystal that includes a superior Raman scattering effectiveness and a robust Raman spectrum, which makes it well suited for A selection of Raman applications.
Request RP Photonics for almost any information regarding tungstate lasers, such as femtosecond lasers and large-energy lasers.
The two-pump laser could give as much as 120 W power. Approximately 60% of the utmost pump electric power was used inside our experiment looking at the reduced functionality from the dichroic mirrors. Beneath this twin-crystal configuration, our cavity supports a one hundred W pump power enter, as discussed in Part two.two. Higher-good quality dichroic mirrors will probably be employed Sooner or later, and laser click here pulses will be stretched to an extended pulse duration.

Tungstates have a tendency to own high Raman coefficients (�?Raman scattering). Hence, they will produce sizeable Raman obtain at average optical intensities. It can be done to utilize the laser crystal alone as a Raman converter.
The scattered photons have another wavelength and Electrical power compared to the incident photons, which makes a Raman spectrum.
