Past function confirmed that the twin-crystal configuration can be employed to compensate to the thermal lensing impact[

We made use of a transmission grating (TG) being a dispersive ingredient in our stretcher and compressor. A compact configuration was adopted, wherever the stretcher as well as compressor shared one particular grating similar to that in Ref.
In its elemental kind, potassium provides a silvery grey metallic appearance, but its compounds (like potassium hydroxide) are more often Employed in industrial and chemical applications.
The datasets made use of and/or analysed all through The existing study readily available through the corresponding creator on reasonable ask for.
The comparison with glasses is appropriate Because the large attain bandwidth lets e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
The other was put with its Np -axis parallel While using the s-polarized route. A comparison was created between a configuration While using the crystals placed in precisely the same orientation (
KGW (potassium gadolinium tungstate) is really a crystal that is often employed like a Raman crystal in Raman spectroscopy. This is a colorless, transparent crystal that includes a high Raman scattering performance and a powerful Raman spectrum, rendering it ideal for A variety of Raman apps.
Inquire RP Photonics for any assistance relating to tungstate lasers, which include femtosecond lasers and substantial-energy lasers.
We formulated a diode-pumped Yb:KGW regenerative amplifier as being the entrance finish in the kilohertz terawatt laser program. Wide bandwidth pulses ended up acquired by applying twin crystals with diverse orientations of their optical axes[

Considering the fact that its discovery in 19701,2, the point out on the art of supercontinuum (SC) era in bulk good-point out resources has arrived at a superior standard of maturity thanks to incredible development of ultrafast laser resources and elementary comprehension of the fundamental physical processes3,four. The complexity of Actual physical effects underlying SC technology is unveiled in the framework of femtosecond filamentation, which happens to be a universal phenomenon arising from nonlinear propagation of femtosecond laser pulses in transparent materials5. In additional sensible terms, the attainable spectral extent of SC radiation will depend on the material Qualities, like linear and nonlinear indexes of refraction and Power bandgap, which together with the laser wavelength define the critical power for self-focusing (that has being exceeded for a light filament to variety) and clamping depth of a light-weight filament (and that is proportional to the order of multiphoton absorption), respectively.
