Laser is a kind of light that does not exist in nature and is emitted due to excitation. It has the characteristics of good directionality, high brightness, good monochromaticity and good coherence.

Semiconductor lasers, also known as laser diodes, are lasers that use semiconductor materials as working materials. It has the characteristics of small size and long lifespan, and can use simple injection current to pump its working voltage and current compatible with integrated circuits, so it can be monolithically integrated with it. Due to these advantages, semiconductor diode lasers have been widely used in laser communications, optical storage, optical gyroscopes, laser printing, ranging and radar.

In recent years, market demand has promoted the development of technology. Nowadays, when electronic products are becoming more and more refined, traditional soldering iron welding and wave soldering can no longer meet the welding of all electronic products.

Recently, some researchers have discovered that blue light can weaken a particularly annoying "super bacteria" and make it again affected by mild fungicides.

Recently, scientists have discovered through research that irradiating a near-infrared laser to adult stem cells derived from human fat can increase the replication speed of stem cells by 54%, and using green lasers can transform stem cells into different types of cells at a faster rate. . Under laboratory conditions, continuous laser irradiation of adult stem cells will lead to increased proliferation and differentiation.

The laser used for measurement is much more accurate than a standard tape measure, and allows you to simply place and measure, rather than actually measuring the distance between points.

Laser has the four characteristics of good directivity, coherence, monochromaticity and high brightness (high optical power density), which are the reasons why lasers are widely used in many fields.

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.
