White papers offer detailed tech
specs on many products
Our library of technical white papers delves into performance
attributes of several optics and photonics products
available on the market, including high-power, fiber-coupled diode lasers, miniature spectrometers,
and optical bandpass filters, to name a few.
Slide shows engage
with cool topics
Whether they are three-point kinematic mounts
or another form such as flexure or gimbal
mounts, tip/tilt mounts are an essential part of
many optical setups. In this Slide
Show, senior editor John Wallace
highlights some of the many tip/
tilt optical mounts available today.
Focus on Lasers & Sources
Laser Focus World covers the design and
applications of all types of lasers, amplifiers,
and other advanced sources like light-emitting diodes (LEDs). Here are two of
our most popular articles on this topic.
Wafer-level LED chip emits 157 W of
A team of Chinese researchers has created a
wafer-level LED chip that produces 157 W of
blue light from an emitting region approximately
30 mm in diameter. What’s more,
the group expects that much
larger chips developed over the
next decade will lead to light
outputs in the tens of kilowatts.
Blue direct-diode laser emits 50 W
Researchers in Japan have created a blue-
emitting direct-diode laser that focuses light
from 30 individual 450-nm-emitting laser diodes
into an optical fiber with a 100-μm-
diameter core; the direct-diode laser
produces 50 W of optical power at
a numerical aperture (NA) of 0.2.
