…hazardous lithography chemicals. Because of these benefits, CO 2 lasers have been used extensively for drilling vias in microelectronics packaging applications for some time. However, the long infrared wavelength of CO 2 lasers limits their minimum focused spot size (due to diffraction). The result…

…visible spectrum, lasers emitting at other wavelengths, such as the very important mid-infrared (MIR) region, require
beam analysis, too. To cover all eventualities, Ophir-Spiricon's Pyrocam broadband thermal camera analyzes pulsed or
continuous-wave (CW) lasers with output from extreme-UV…

…material removal (FIGURE 1).
Of currently available ultraviolet laser
technologies, pulsed excimer lasers offer
the highest pulse energy (up to 2 J). Plus,
the large rectangular beam produced by
excimer lasers can easily be shaped and
homogenized to match the geometry…

…knife-edge-based)?
The primary factors which determine the type of beam profiler to
use are wavelength, beam size, laser power (or energy) and
operating mode (CW or pulsed).
Wavelength
The wavelength being measured largely determines the type of
detector device needed.…

…CO lasers lead to significant benefits in some important commercial applications. Mid-IR wavelength advantages CO lasers output in the 5 µm spectral range which offers two important advantages for some applications compared with the long-wave infrared (10.6 µm) output of the widely used CO 2 laser.

…ultrafast processing and processing with longer
pulsewidth lasers.
Picosecond regime, ultra-short pulse (USP) lasers operating at 532 nm (green) are now emerging as
alternative technology to UV nanosecond lasers in package cutting applications because they often
deliver superior…

…resurfacing uses a 1550 nm diode laser together
with an infrared CO
2
laser at 10.6 µm,
in a procedure called "fractional resurfacing" (Fig. 4). In this two-pronged
approach, the CO
2
laser is focused to
a small spot and pulsed as the spot is
moved across…

…in a pulsed or continuous
mode, the infrared CO2
laser beam is invisible to the human eye.
Optical radiation in the CO2
laser wavelength range is absorbed by
the cornea. As a result, corneal burns are a likely result if the eye is
exposed to a CO2
laser beam.…

…process using the CO
2
laser. The CO laser can cut thin glass
(in the 50 µm to 300 µm thickness
range) directly, without the need for an
air or water cooling jet often required
in tandem with the CO
2
laser. The CO
laser not only eliminates the need for a…

pulse duration generally reduces the ablation threshold. This means that the required pulse energy decreases as the pulse duration decreases. The advantage of this is that a lower pulse energy leads to less unwanted heating. A second benefit of shorter pulse widths is that more of the absorbed laser

…attosecond physics so let's start there.
CEP stabilization makes it possible to
generate ultra-short laser pulses with
reproducible wave form of the electric field, down to pulse lengths of just
a single optical cycle. Ferenc Krausz
and others have done amazing work
