Applications of Laser Power Supplies in Precision Machining

In precision machining, different laser power supplies are chosen for specific applications based on their unique characteristics.

CO₂ Laser Power Supplies

CO₂ laser power supplies are primarily used for processing non-metallic materials. Their 10.6μm wavelength offers high absorption rates for organic materials, making them ideal for acrylic precision cutting, PCB micro-hole drilling, and medical catheter forming. With high power stability, they ensure smooth, slag-free cutting edges. Additionally, CO₂ lasers excel in glass engraving and ceramic micromachining, enabling intricate 3D structures through precise power modulation (response time <1ms).

Fiber Laser Power Supplies

Fiber laser power supplies are the preferred choice for metal processing due to their superior beam quality and high electro-optical efficiency. For example, 6kW continuous fiber laser power modules deliver stable high power, rapid response, and efficient energy conversion, making them suitable for thick metal cutting, welding, laser cladding, and processing highly reflective materials.

Semiconductor Laser Power Supplies

Semiconductor laser power supplies, such as short-pulse and long-pulse models, are compact and energy-efficient. They are commonly used for plastic welding and surface heat treatment, such as sealing automotive sensor housings or hardening gear teeth. Their adjustable wavelengths accommodate various material absorption spectra. Short-pulse semiconductor lasers (microsecond-level) with high peak power and ultra-short interaction times are ideal for micro-marking electronic components, precision thin-film stripping, and non-destructive processing of brittle materials. Long-pulse semiconductor lasers are widely used in precision electronic welding, metal surface modification, and medical device plastic welding.

ND:YAG Laser Power Supplies

ND:YAG laser power supplies are known for their high peak power (kilowatt-level) and microsecond pulse control, making them ideal for challenging metal micromachining tasks. Examples include drilling clustered cooling holes in aerospace engine blades or etching textures on precision molds. Their short-pulse characteristics minimize thermal distortion.

By leveraging these four types of laser power supplies, manufacturers can address a full spectrum of needs—from micron-level cold processing to large-scale precision manufacturing—driving the industry toward higher efficiency and lower material damage.
