Embodiment Construction

[0022] The technical solution of the laser energy control method and system will be described in detail below in conjunction with specific embodiments and accompanying drawings, so as to make it more clear.

[0023] Such as figure 1 Shown, in one embodiment, a kind of laser energy control method, comprises the steps:

[0024] Step S110, acquiring the average emission power of the laser.

[0025] In this embodiment, the emission energy of the laser is sampled in real time through a preset frequency, and then the average emission power of the laser is calculated according to the emission energy. The average transmit power is a more accurate representation of the laser's transmit power. Lasers can be CO 2 Lasers (carbon dioxide lasers), YGA lasers (YGA, yttriumaluminum garnet, yttrium aluminum garnet), semiconductor pump lasers and other lasers. The average emission power of the laser can be obtained through laser energy or power testing equipment such as a laser power tester...

Abstract

The invention provides a laser energy control method and a system. The method includes obtaining average transmission power of a laser, comparing the average transmission power with preset power in a storage and adjusting a laser transmission pulse duty ratio of the laser to enable the average transmission power to tend to the preset power according to the comparison result. According to the laser energy control method and the system, the average transmission power and the preset power in the storage are compared by obtaining the average transmission power of the laser, and the laser transmission pulse duty ratio of the laser is adjusted to tend to the preset power according to the comparison result, so that the average transmission power of the laser is stable, marked colors and depth are uniform during laser marking, and the processing quality and the processing efficiency are improved.

Description

technical field [0001] The invention relates to control technology, in particular to a laser energy control method and system. Background technique [0002] The original Chinese name of laser is "Laser" and "Laiser", which is the transliteration of its English name LASER. Stimulated emission light expansion". The full English name of laser expresses the main process of manufacturing laser. In 1964, according to the suggestion of Qian Xuesen, a famous scientist in my country, "light stimulated emission" was renamed "laser". [0003] The characteristics of laser are directional light emission, extremely high brightness, extremely pure color and extremely high energy density. Lasers are widely used, mainly including laser marking, optical fiber communication, laser spectrum, laser ranging, laser radar, laser cutting, laser weapons, laser discs, laser pointers, laser vision correction, laser beauty, laser scanning and laser mosquito killers etc. [0004] Laser marking is a ...
