Polarization maintaining fiber is a special type of fiber that can maintain the linear polarization characteristics of linearly polarized light during fiber transmission, suitable for situations where the linear polarization state of the optical signal needs to be maintained. Single mode fiber is a type of fiber that can transmit a single optical mode with minimal transmission ...

The safety level of lasers is generally divided into four levels, which are based on the degree of damage to the human body caused by the laser generated by the laser. Grading from class I (no damage) to class IV laser.

Narrow Linewidth Laser is a specially designed laser with a very narrow spectral linewidth. It plays an important role in many application fields, including optical communication, fiber optic sensing, spectral analysis, and so on. The high-quality optical output and stability of narrow linewidth lasers make them key components for achieving precision measurement and high-speed ...

A semiconductor laser is a device that uses semiconductor materials to generate lasers. It has the advantages of small size, high efficiency, and low power consumption, and is widely used in fields such as communication, medical treatment, material processing, and fiber optic sensing. The working principle of semiconductor lasers is based on the characteristics of semiconductor...

The application fields of lasers include seven fields: industrial field, medical field, communication field, environmental field, security field, life field, military field, etc. Our convenient life is already inseparable from and inseparable from the use of lasers, and the development of technology has already surpassed our reality.

Laser is the abbreviation for "Light Amplification by Stimulated Emission of Radiation", which refers to the enhanced photon beam generated by stimulating atoms to release radiation energy through electron transitions. Compared with other types of light, laser has a series of characteristics, such as low divergence, high brightness, good monochromaticity, good coherence, etc., ...

Definition: An amplifier that amplifies ultrashort optical pulses. Ultrafast amplifiers are optical amplifiers used to amplify ultrashort pulses. Some ultrafast amplifiers are used to amplify high repetition rate pulse trains to get very high average power while the pulse energy is still at moderate levels, in other cases lower repetition rate pulses get more gain and get very ...
