A superradiance light source (also known as an ASE light source) is a superradiance-based broadband light source (white light source). (It is often mistakenly called a superluminescent light source, which is based on a different phenomenon called superfluorescence.) Generally, a superluminescent light source contains a laser gain medium that is excited to radiate light and then amplified to emit light.

The fiber optic sensor network has three basic components, one of which is called a single-point sensor. An optical fiber only plays the role of transmission here, and the other is called a multi-point sensor, where one optical fiber connects many sensors together so that many sensors can share the light source to realize network monitoring. Then there is the smart fiber optic sensor. The multi-point optical fiber sensor is a grating from the outside, and periodic intervals are found through ultraviolet irradiation. When an optical fiber is incident, if the wavelength of the optical fiber is exactly twice the interval, the light wave will be strongly reflected, and if the optical fiber is subjected to temperature changes or strains, the reflected wavelength will change. This kind of sensor There can be many on one fiber, and it can be used for a variety of sensing applications by connecting them.

At the Laser World Expo in Munich, TRUMPF, the world's leading industrial laser manufacturer, presented an innovative system solution designed to improve the quality and efficiency of laser welding processes. The solution integrates multiple sensors to monitor key points in the welding process in real time.

When linearly polarized light is incident precisely along one of the principal axes (slow axis or fast axis), due to the huge difference in propagation constants between the two orthogonal polarization components, almost no energy coupling occurs between them, thereby maintaining the incident polarization state.

A gas detection laser is an instrument that uses laser technology to measure gas concentration. It emits a laser beam into the gas and then analyzes the absorption or scattering of the laser beam to infer the gas concentration. This method has high sensitivity and accuracy, and can achieve rapid, online monitoring of specific gases.
