coherent.com. The optical wavelength of the laser output is
1064 nm (IR, infrared). An additional frequency conversion to
532 nm (SHG, green) and 355 nm (THG, UV) is optionally
possible. The output…

DPSS lasers also emit
in the near infrared.
Generally, these lasers
are more expensive than
a fiber laser of the same
output power level. So,
infrared DPSS lasers are
most commonly used
in applications having…

Picosecond laser marking
With picosecond lasers, the pulse duration
is typically shorter than the time for heat to
flow out of the laser interaction zone, even
in metals, so peripheral thermal effects
are greatly reduced compared to nanosecond lasers. This means that a…

laser rapidly emerged as an
ideal source for this application because
it can produce blind vias using a simple,
three-pulse process. The first pulse drills
through the overlying copper, which has
a black oxide coating on it to make it absorb infrared (IR). The second pulse

The Astrella amplifier is used, for example, in 2D infrared (IR) spectroscopy.
"Conventional infrared absorption spectra are usually obtained from a Fouriertransform infrared (FTIR) instrument,"
says Henrich.…

…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).

The wavelength being measured largely determines the type of
detector device needed.…
