Laser Source Selection For Laser Marking
Product Description
A laser is a device that uses the principle of stimulated radiation to amplify or oscillate light in certain excited substances. Light, electricity, and other methods are used to excite the material, so that some of its particles are excited to a state with higher energy. When the number of particles in this state is greater than the number of particles with lower energy, the material can A certain wavelength of optical radiation produces amplification, that is, when the optical radiation of this wavelength passes through the substance, it will emit optical radiation that is amplified in intensity and consistent with the incident wave position, frequency and direction. This device is called a laser amplifier. If the excited substance is placed in the resonant cavity, the optical radiation will reciprocate in the resonant cavity along the axial direction, and it will pass through the material multiple times. The optical radiation will be amplified many times to form a beam of laser light with high intensity and concentrated direction.

Sino Galvo's laser has the advantages of high efficiency, compact structure, good beam quality, stable performance and long life. It can be directly applied to marking of various materials such as plastic and metal.
Laser of this series is marked as Class IV. Laser directly cast will cause irreparable harm to eyes, skin and objects burnt. In some cases, scatter and reflection of laser are also likely to harm human bodies.
This product emits approximately 1060nm wavelength invisible laser with high power.
Avoid any direct or scattered output laser contact with eyes or skin.
Goggles are necessary when working with the laser.
Do not open the housing. There is no part of the product that can be fixed by our clients. Repairs and maintenance should take place at Sino-Galvo (Jiangsu) Technology.
