Dual-Channel Lock-in Amplifier OE1022D Applied in the Study of Nonlinear Plasmon-Exciton Polarit
In 2022, the research team led by Professor Jiang Tian from the National University of Defense Technology, in collaboration with Professor Shi Lei's team from Fudan University, published an article titled "Interacting Plexcitons for Designed Ultrafast Optical Nonlinearity in a Mono" in RLight: Science & Applications.
Terahertz Time Domain Spectroscopy and Frequency Domain Spectroscopy
Terahertz time-domain spectroscopy characterizes material properties by measuring complex responses in the frequency range from terahertz to tens of terahertz. In this frequency band, various resonance phenomena such as electron and phonon excitations in solid materials are usually observed.
Application of Lock - in Amplifier in TDLAS Technology
In the laser phase-locked system, the most crucial part is the use of lock-in amplifier to achieve the test gas, reference gas two-way detection, or even to achieve the measured gas, reference gas and laser background three-way detection.
Application in Photo Acoustic Spectroscopy
Photo Acoustic Spectroscopy (PAS) is an analytical instrument with a mechanism similar to that of a secondary quantum optical spectrometer.
