…of an intense laser pulse. It generates an optical field at double the frequency of the original laser beam, with the
result that part of the incoming laser power will be converted to half the original wavelength (second-harmonic generation (SHG) or frequency doubling)
(Figure 9). Since…

…property. One example is
the PowerLine Pico 10 from Coherent Rofin which
generates 0.5 ns laser pulses in either the near IR (8
W total power) or green (3 W total power), at pulse
repetition rates between 300 kHz and 800 kHz.
This combination of output characteristics makes…

…laser annealing (ELA; see Fig. 3). Specifically, a pulsed
excimer laser line beam is scanned over
the a-Si film, which efficiently absorbs the
308 nm excimer output.
This high absorption, combined with
the high pulse energy of the excimer laser,
makes it possible…

…generates very short and intense pulses. However, it limits how fast the laser can be
modulated (turned on and off). And, just as important, it causes noise problems when using
frequency conversion to generate harmonics of the fundamental, e.g., doubling the 1064 nm
fundamental…

…big systems achieve performance

That precision comes at a price. Specifically, each
pulse takes only a tiny nibble of material, which means
that a whole lot of pulses are needed for machining. Ultrafast lasers generally run at repetition rates of hundreds
of kilohertz…
