Laser Ablation
Laser Ablation for Crystal Application
Laser ablation is a process in which a high-intensity laser beam removes material from a solid surface by rapidly heating, vaporizing, or even ionizing the target area. This technique is widely used for material processing, micro-machining, and surface structuring in various scientific and industrial applications. The efficiency and precision of the ablation process depend on several factors, including the laser wavelength, pulse duration, and energy density
In our laboratory, we utilize two distinct laser systems: the Keyence MDU1000C, which operates in the ultraviolet (UV) range, and the MDX2020A, which works in the infrared (IR) spectrum. The UV system is particularly effective for high-resolution work due to its shorter wavelength, which allows for finer feature control and minimal heat-affected zones, making it ideal for delicate or precision-critical applications.
In contrast, the MDX2020A IR laser system is designed for applications that require deeper penetration and more robust energy delivery. The IR wavelength generally interacts differently with materials, offering advantages in scenarios where bulk material removal or processing of materials with lower UV absorption is necessary. This system is well-suited for tasks where the goal is to achieve substantial ablation depths or when working with substrates that benefit from the thermal characteristics of IR radiation. By combining the strengths of both the UV and IR laser systems in our lab, we can tailor our approach to suit a wide range of materials and processing requirements, thereby optimizing the ablation process for each specific application.
Conclusion:
Laser ablation is a versatile technique that benefits greatly from the careful selection of laser parameters, particularly wavelength. The dual-system setup in our lab—with the Keyence MDU1000C providing precision via UV radiation and the MDX2020A offering deep, efficient processing through IR radiation—enables us to address a broad spectrum of material processing challenges. This complementary approach not only enhances the quality and efficiency of ablation but also expands the potential for innovative applications in research and industry.
