In its many configurations, the CAOS camera images laser beams in different ways that match differing system requirements.

An electro-optically modulated continuous-wave laser produces pulses every 100 ps with sub-optical-cycle accuracy, resulting in a frequency comb useful for biological imaging....

Optical gas imaging (OGI) cameras rely on changes in infrared (IR) radiation as it passes through a gas. The technique is still relatively new and no official standard yet exists...

Nominal 2 µm thulium fiber lasers have only reached repetition rates up to 1.6 GHz. However, active mode locking extends this rate more than an order of magnitude, making communications...

Spin-orbit coupling of light in the emission of elliptically polarized emitters can cause wave-length-scale positioning errors.

Editor in chief John Lewis welcomes back contributing editor Jeff Hecht and discusses November issue content, including laser weapons and automotive lidar.

Changes in the global economic and political situation are being to affect laser markets, but the real consequences are only beginning to emerge.

Because of sub-nanometer precision, active piezo shims cover applications in precision engineering and optical element alignment.

Many optical materials exist for designing IR optics; chalcogenide BD6 has some advantages when compared with legacy materials.

Optogenetics has rocked the world of neuroscience for more than a decade now. But neuroscientists want more from the technique—and less, including more depth and less invasiveness...

Now approaching luminance of 100 million nits, phosphor-converted LEDs target applications that not only con-vey concentrated illumination at low cost, but also transmit information...

The overlap is large between automotive lidar and familiar names in the photonics industry.

The involvement of industry partners and clients in the new product development process directly benefits the scaling of perovskite PV technology from the lab to commercial and...
