Exploring Cutting-Edge Applications in Microfluidics, Biomedicine, and Photonics
đź”· Introduction
In recent years, femtosecond laser micro-nano fabrication has emerged as a transformative technique for building intricate three-dimensional (3D) structures with submicron precision. With ultra-short pulse durations and high peak power, femtosecond lasers enable non-thermal, high-precision material processing through nonlinear absorption—even within transparent substrates like glass and sapphire.
As demands grow for integrated microfluidic platforms, biocompatible devices, and chip-scale photonic circuits, femtosecond laser systems provide an ideal solution for advanced fabrication across both academic and industrial applications.
🟢 Microfluidics: 3D Glass Structuring for Lab-on-a-Chip Applications
Femtosecond laser-assisted selective etching (FLASE) is revolutionizing the field of microfluidics. By precisely modifying the internal structure of glass followed by chemical etching, complex 3D microchannel networks can be fabricated without layer-by-layer bonding or masks.
Application Highlights:
- Transparent 3D microfluidic chips for biomedical assays
- Embedded channels for droplet control and chemical synthesis
- Glass–silicon hybrid integration through laser bonding
Our Equipment Advantage:
Our femtosecond laser direct-writing system supports sub-100 nm positioning accuracy with full XYZ or XYZT air-bearing stages, enabling large-area, high-uniformity 3D glass structuring. The platform integrates advanced motion control with PSO (Position Synchronized Output), real-time machine vision, and autofocusing modules for optimal fabrication quality.
🟡 Biomedicine: 3D Printing of Microrobotic Components via Two-Photon Polymerization
Two-photon polymerization (TPP) enabled by femtosecond lasers allows for true 3D freeform printing with nanometric precision. This technology is particularly valuable in biomedical engineering where complex, biocompatible structures are required.
Application Highlights:
- High-aspect-ratio microneedles
- Bio-scaffolds for tissue engineering
- Soft microrobots for targeted drug delivery
Our Platform Delivers:
With stable femtosecond sources offering tunable pulse widths (290 fs–10 ps), burst mode operation, and CEP options, combined with multi-axis precision stages and programmable optical fields (e.g., Bessel, vortex, cylindrical vector beams), our system supports ultra-fine polymer structuring in photoresists like IP-Dip and IP-L.
đźź Photonic Devices: Embedded Waveguides and Polarization Elements
Femtosecond laser direct writing enables refractive index modification, nanograting inscription, and localized birefringence tuning within bulk glass—without surface damage or intermediate layers.
Application Highlights:
- Low-loss optical waveguides in JGS1 or borosilicate glass
- Embedded nanogratings for phase and polarization control
- Monolithic optical interconnects for photonic packaging
Technical Strengths: Our system supports DXF and STL file imports, spiral path planning, and real-time adaptive focus tracking. It can generate structured vector beams via a programmable SLM (spatial light modulator) or DOE, making it ideal for writing high-performance photonic elements inside transparent materials.
