... The MTF uses the power density (W/cm2 or (J/sec)/cm2). The resist responds to the total amount of energy absorbed. Thus, we need to define the Dose, with units of energy density (mJ/cm2), as the Intensity (or power density) times the exposure time. • We can also define D100= the minimum dose for whi ...

Phonon Laser Action in a Tunable Two-Level System
... conditions there (and typical of Brillouin scattering in the traveling-wave geometry), however, feature stronger spatial damping of the phonons compared to the photons and therefore make clear that optical amplification was observed [26]. Lower temperature operation could alter this balance [26]. Th ...
