Dry fire training is a simulation bullet made from laser bullets, which like real bullets, can practice standing posture, gun display, line of sight alignment, aiming chart, breathing control, and pulling the trigger.

Cross line laser intensity is very high, suitable for using a remote location and poor working environment, the product USES the original laser diode, long service life, good stability, constant power output, small volume, convenient installation, can work long time continuous light, can effectively guarantee the stability of the product and service life.

Laser pointers are usually used as an eye-catching point in education, business presentation, and visual demonstrations. Laser pointer is harmful to human eyes.

In industrial applications, infrared lasers have achieved very good results in many aspects. However, for the processing of non-ferrous metals, especially copper, due to its low absorption rate of laser in the wavelength range of infrared light, the welding process is often unstable, and welding errors in production often lead to waste, so infrared light is not suitable for the welding of non-ferrous metals.To achieve high absorption, it is ideal to use blue light with a wavelength of 450nm.

“Laser” stands for “Light Amplification by Stimulated Emission of Radiation". Laser emits light coherently which allows a narrow spectrum laser beam and a focused light spot on a targeted surface.

Fiber lasers refer to the use of rare earth doped glass fiber as the gain medium laser fiber laser can be developed on the basis of fiber amplifier; Under the action of pumping light, the high power density is easily formed in the fiber, resulting in the "particle number inversion" of the laser energy level of the laser working material.

A blue laser diode is a semiconductor laser that produces a concentrated photon beam with a wavelength of about 400 to 500 nanometers-the visible electromagnetic spectrum that the human eye perceives is blue or violet.

Laser is especially suitable for material processing because of its characteristics of monochromatic, coherence and parallelism. In addition, its good space control and time control, processing object material, shape, size and environment of freedom are very large, especially suitable for automatic processing.

The technology of semiconductor laser develops comprehensively, and it is more competitive as the light source of laser display. Semiconductor lasers can be directly excited by current, which is more efficient than solid-state lasers. The working material attenuates slowly and has a longer service life; The light source system is smaller and suitable for high integration; Mass production with a semiconductor process can make the device cost lower.

A laser generally consists of three parts.laser working medium, Incentive source, resonant cavity. Lasers are classified according to power into Class I, Class II, Class IIIA, Class IIIB, and Class IV.
