Abstract

The invention relates to the technical field of laser output equipment, and provides a laser collimator and a laser system. The laser collimator comprises an optical fiber, a first lens and a second lens; the optical fiber, the first lens and the second lens are sequentially arranged and distributed in the axis direction of the optical fiber; a through hole is formed in the first lens, and the through hole penetrates through the first lens in the axis direction of the optical fiber; and the first lens includes a first concave surface, and the first concave surface faces the second lens or theoptical fiber. The laser collimator and the laser system can effectively reduce the adverse effect of the return light on the laser system and improve the stability and security of the system operation.

Description

technical field [0001] The present invention relates to the technical field of laser output equipment, in particular to a laser collimator and a laser system. Background technique [0002] Fiber lasers are lasers that use rare-earth-doped glass fiber as the gain medium. Due to its low cost, miniaturization, and obvious advantages of intensification, and its high electro-optical efficiency and power, it has a wide range of applications. And, with the development of high-power fiber laser applications, fiber lasers are widely used in parts marking, cutting, drilling, welding, cleaning and medical surgery. The most common ones in the market are used for laser marking, laser cleaning, and different processing materials. In the process of laser application, the intensity of the returned light is also different. The higher the power of the laser, the stronger the return light will be. Excessive return light can easily cause damage to the system and even damage the laser. There...
