Recently, the Advanced Laser and Optoelectronic Functional Materials Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made progress in the research of Nd: ASL (Sr0.7Nd0.05La0.25Mg0.3Al22.7O19) laser crystals, and the related achievements were published in Infrared Physics&Technology under the title of "Tunable laser operations on Nd doped cont...
Topological laser (TL) is a laser device designed and manufactured using the principles of topological optics, which can produce a robust single-mode laser and is an ideal light source for future new optoelectronic integrated chips. Electrically pumped topology lasers have become a research hotspot due to their small size and ease of integration, but topology lasers based on electrical injection a...
Researchers printed microscale lenses directly onto optical fibers, allowing them to tightly combine the fibers and laser crystals into a single laser oscillator.Scientists have used 3D printing polymers in new micro optical technology, which can reduce the size of lasers and be used in various new applications, including the laser radar system for autonomous vehicle technology and cancer treatmen...
Holographic display technology provides the ultimate solution for true 3D display, with enormous potential in augmented reality and virtual reality. However, the color and viewing angle of holographic 3D displays mainly depend on the wavelength of the laser and the pixel size of the current spatial light modulator. The inevitable color difference and narrow viewing angle in conventional systems se...
The new device is a frequency comb - a special type of laser that can generate multiple wavelengths of light, each with a fixed frequency interval. On the spectrogram, it looks a bit like the teeth of a comb. In approximately a quarter century since their first development, these "cursor rulers" have completely transformed various high-precision measurements from timing to molecular detection. In ...
