Advances in high-energy solid-state lasers and encouraging results from field trials show expanded capabilities of recent U.S. military laser prototypes.
Adding hyperspectral imaging capability to a standard medical endoscope allows capture of retinal images that reveal soluble amyloid aggregates linked to Alzheimer’s disease.
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...
Editor in chief John Lewis welcomes back contributing editor Jeff Hecht and discusses November issue content, including laser weapons and automotive lidar.
Because of the down-to-nanometer-range resolution of their piezo elements, active shims cover applications in precision engineering and alignment of optical components.
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 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...
