Abstract

The invention discloses a double beam coupling device, which includes a collimation system used for collimating Nd:YAG laser and enabling the collimated laser beam to form a beam of parallel light, a first 45-degree reflector used for reflecting and changing the transmission direction of the Nd:YAG laser, a beam expanding system used for expanding the Nd:YAG frequency-doubled laser and obtaining light beams with different divergence angles, a second 45-degree reflector used for changing the transmission direction of the Nd:YAG frequency-doubled laser through the Nd:YAG laser and reflection, and a focusing system used for coupling and focusing the Nd:YAG laser and the Nd:YAG frequency-doubled laser to one position. The device overcomes the difficulty in welding processing by adopting the single Nd:YAG laser, and greatly improves the welding efficiency and the welding quality.

Description

technical field [0001] The invention relates to a device for coupling and focusing two beams of laser beams with different wavelengths, in particular to a double-beam coupling device for welding with two laser beams of different wavelengths. Background technique [0002] In the past ten years, laser has been widely used in industrial production, especially for metal welding, cutting, drilling, marking and surface treatment. In production, laser welding technology is becoming more and more important, which is mainly due to the high precision, high processing rate, low thermal stress on the workpiece and the degree of automation that laser welding can achieve. Laser welding technology is gradually replacing traditional welding technology, especially in the production and processing of high value-added products, laser welding technology is unmatched by traditional welding technology. [0003] There are generally two types of laser light sources most widely used in current lase...
