The wavelength selection of laser in the underwater field is [...]
Laser has the characteristics of monochromaticity, high brightness and collimation, and is widely used in various fields such as industrial production. Laser ranging is a method of distance measurement using laser technology. It calculates distance by measuring the time it takes for a laser pulse from a laser to reach the target and back. Advantages of [...]

Laser is light that is amplified by absorbing radiant energy. A laser is a device that generates and amplifies a laser beam. All lasers contain three components: pump source, excited medium, and resonant cavity. The principle of laser: The pump source supplies external energy to the laser, and the excited medium is located inside the [...]
The optical part of the dust meter includes laser light source, power control, photoelectric sensing, and scattered light receiving part. The principle of laser dust detection is that the beam emitted by the laser enters the emission source at a slight angle. The laser beam interacts with the smoke particles to produce scattered light. The backscattered [...]
A line laser is a device that uses a laser and optical lenses to project a laser beam as a line rather than a point. It is often used in dimensional measurements to provide a reference line for measuring the size of an object. The principle of the line laser is the refraction of light. By [...]
Laser positioning is an application technology that uses laser beams to assist positioning without contact. It usually uses a laser to emit laser spots of different shapes, and uses the position and shape of the spot to assist measurement and positioning. Types of laser positioning: One-line laser positioning That is, a straight line, the diameter of [...]
Blue laser refers to a laser located in the blue band light source, with a wavelength in the range of approximately 400 nm-500 nm. Blue-ray laser has the characteristics of short wavelength, small diffraction effect, and high energy. It has broad application prospects in material processing, optical information storage, display technology, communication technology, laser medical treatment, [...]
The laser cutting machine focuses the laser light emitted from the laser into a high power density laser beam. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam will melt or vaporize. As [...]
