…4: Schematic illustration of the setup used to generate EUV pulses. Inset shows the
recorded spectrum of the EUV pulses when the HHG gas is helium with an optimized input pulse
energy of 6m. The spectral bandwidth (FWHM) of the different harmonics is approx. 0.75 nm.

Coherent Whitepaper - Astrella Tisch Sphere FINAL.pdf

…Increased output power can
be achieved using helium as the nonlinear medium, which has a greater ionization potential but
also has a lower nonlinear index, i.e., lower SPM efficiency. Using 3.4 bar (at the HFC exit) of
helium as the nonlinear medium, they then achieved 6 fs pulses…

…driven by short pulses. Hence there is interest in using
milder driving pulses which are easier to generate. In terms of the inert gas fill, helium can handle
the highest input power whereas neon can deliver the broadest visible continuum. Based on the
8 mJ pulse energy from the…

…these lower
vibrational energy states, the CO
2
molecules transition ultimately to the lowest energy state through collisions with helium,
that is, through vibrational-translational
(V-T) energy transfer. From this lowest
energy state, they can then be re-excited.

…chronicling major technology milestones. Among the trends, it's interesting to note that some laser technologies, such as ruby, nitrogen, and helium cadmium (HeCd), may have generated initial excitement, but at best penetrated only a few niche markets. Rather, the bulk of today's multibillion-dollar…

…mixing yields a range of wavelengths that can cover 200 nm to 20 µm.
Common laser types
For many years, the most common CW laser was the helium neon laser, or HeNe. These low-power lasers (a few milliwatts) use an electric discharge to create
a low-pressure plasma in a glass tube;…
