Anhui Institute of Optics and Fine Mechanics (AIOFM) · Research ProgressOptics industryAI score4949 Hefei Institutes Develop Dual-Differential Sphere-Tube Coupled Photoacoustic-Scattering System for Simultaneous Aerosol Optical Measurements
A team led by Researcher Fang Yonghua at the Hefei Institutes of Physical Science has developed a dual-differential sphere-tube coupled photoacoustic-scattering system that simultaneously obtains aerosol absorption and scattering coefficients at 450 nm and 532 nm within a single sampling path and shared measurement volume. The results were published in Photoacoustics. Two laser beams are modulated at 2572 Hz and 169 Hz and demodulated by frequency using an FPGA-based digital lock-in amplifier. With a 1 s integration time, detection limits for the 532 nm absorption and scattering channels are 1.2 Mm⁻¹ and 1.32 Mm⁻¹, respectively.

Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) · Research ProgressOptics industryPicksAI score6060 Changchun Institute of Optics, Fine Mechanics and Physics Develops Goblet-Shaped Waveguide Mid-Infrared Quantum Cascade Laser with Room-Temperature Low-Power Output
A team led by Researcher Meng Bo at the Changchun Institute of Optics, Fine Mechanics and Physics published a paper in Laser & Photonics Reviews presenting a mid-infrared quantum cascade laser with a goblet-shaped waveguide structure, using selective wet etching of the active region and eliminating the semi-insulating InP lateral regrowth process. A 1 mm x 3 um device achieved a continuous-wave threshold power consumption of about 1 W at 293 K, an output power above 27 mW, and a room-temperature pulsed wall-plug efficiency of 3.9%. A 2 um-wide device achieved stable single-mode lasing across the entire current range, with a side-mode suppression ratio of about 20 dB.
Why we recommend it: The goblet-shaped waveguide eliminates the semi-insulating InP regrowth process through selective wet etching. The original paper gives room-temperature continuous-wave threshold power consumption and wall-plug efficiency, which can be compared with buried heterostructure devices for context.
