Nd:YAG Lasers in Microprocessing
Nd lasers (Neodymium-doped Yttrium Aluminum Garnet) operate primarily at 1064 nm in the infrared spectrum. They can be run in continuous-wave or pulsed modes, making them versatile for both material removal and non-thermal processes. Here’s a breakdown of how fiber and solid-state Nd lasers are used in microprocessing.
1. Fiber Nd Lasers
Key Features:
Beam Delivery: The laser beam is generated and transmitted through an optical fiber, providing high flexibility and control over the laser spot size and energy delivery.
Efficiency: Fiber lasers are known for higher electrical efficiency, allowing them to operate at lower power consumption while maintaining strong output.
Precision: Due to their excellent beam quality, fiber lasers excel in processes that require fine detail and consistent accuracy over a large production run.
Applications in Microprocessing:
Micro-Drilling: Ideal for creating micro-holes in metals, ceramics, and plastics. Fiber lasers can drill holes as small as a few microns in diameter, commonly used in electronics and medical device manufacturing.
Micro-Engraving and Marking: Frequently used for detailed engraving on metals, plastics, and ceramics, fiber lasers provide sharp, clear markings ideal for traceability, logos, and intricate patterns.
Micro-Welding: Fiber lasers provide controlled heat input, making them suitable for joining small components without excess distortion. This is especially useful in sensitive applications like medical implants or electronic connectors.
Micro-Cutting: Fiber lasers can cut thin metals, polymers, and ceramics with minimal kerf width and heat-affected zones, ensuring clean edges for intricate designs.
