…means a column of cortex measuring 250 µm x 250 µm, with a depth up to 1 mm. This will require very fast
scanning with fast modulators, or splitting the beam intensity and scanning the tissue with multiple focused spots. Either way, power
is key to obtaining acceptable signal to noise…
…substrates. The alternative method
that emerged was LTPS annealing (FIGURE 1).
In this technique, a pulsed excimer laser line beam is
scanned over the a-Si film. Silicon efficiently absorbs the
308nm excimer output. This high absorption, combined with
the high pulse energy…

scanning the beam and stepping the focus
of the laser, or stepping the sample, a 3D
image can be acquired.
Arrigoni described three distinct benefits associated with MPEF-based applications,…
…Minimizing the heat

Micromachining metals, in contrast, can be accomplished with wavelengths in the visible and IR. But,
again, heat builds up and fast scanning or parallel processing is often…
