High-End Application Scenarios of Femtosecond Laser Processing for Molybdenum: From Aerospace to Medical Equipment

As the demand for "high-precision molybdenum components" surges in the aerospace, semiconductor, and medical fields, femtosecond laser processing technology for molybdenum has become a "key enabler" for high-end manufacturing, thanks to its advantages of "no thermal damage and high adaptability". From 3μm narrow-linewidth molybdenum mesh to precision shafts with Ra < 0.2μm, how does femtosecond laser adapt to different scenarios?  

Optics Field: ±1μm Precision Molybdenum Aperture Processing

• Core Requirement: SEM electron microscope apertures and optical imaging pinholes require "extremely high aperture precision + smooth hole walls" to avoid light spot distortion.  

• Femtosecond Laser Solution: Realizes tolerance-free processing on molybdenum sheets, with aperture roundness > 99%, no burrs/melting marks on edges, and tolerance strictly controlled within ±1μm—perfectly meeting the "micro-scale precision" requirements of optical components.  

• User Value: Compared with traditional photolithography, processing efficiency is doubled, and no mask is needed, reducing the cost of small-batch customization.

1.2 Aerospace Field: 3μm Narrow-Linewidth Molybdenum Mesh Cutting

• Core Requirement: Molybdenum mesh in aerospace equipment needs "lightweight + complex structure + no oxidation" to ensure stability under high temperatures.  

• Femtosecond Laser Solution: Non-contact cutting with a kerf width as small as 3μm, no dross or carbonized layer on the cut edge, and no deformation caused by mechanical stress; it can process complex grid patterns to meet the "lightweight" design needs of equipment.  

• Typical Applications: High-temperature filter molybdenum mesh for rocket engines, molybdenum mesh for cabin pressure regulation—after processing, the high-temperature resistance of the material remains unchanged.

Medical Field: Precision Molybdenum Shaft Herringbone Groove Etching

• Core Requirement: Molybdenum shafts for liquid metal bearings in CT equipment require "smooth herringbone spiral grooves" to ensure the liquid metal forms a uniform supporting liquid film.  

• Femtosecond Laser Solution: Precisely controls the etching depth through ultra-short pulses, with clean and neat groove edges and surface roughness Ra < 0.2μm; non-contact processing avoids shaft deformation, ensuring the "precision" of CT imaging.  

• Problem Solved: Addresses the issues of rough grooves and short service life caused by EDM (Electrical Discharge Machining).
