…wavelength coverage with
the requisite beam quality
for microscopy; thanks to
precision optics inside the
package, diode lasers can
deliver a circular beam
with low astigmatism (a)
and OPSL technology
offers even higher beam
quality and circularity (b).…

…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…

…Minimizing the heat
requires fast scanning of the beam or splitting it up to enable parallel processing.
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…
