Laser Using Scattering Effects TRIZ Cases
- Chromatic Lens Flying Focus Laser Control
Varying wavelength over time shifts the focal location along the optical axis, maintaining small spot sizes beyond Rayleigh length without complex waveguides.
- Multi-Core Optical Fiber Laser for High-Power THz Beat Generation
Merging two laser cores into one fiber eliminates dual-laser complexity while maintaining frequency stability for high-power terahertz generation.
- Multi-channel Laser for Diffuse Optical Tomography
Segmented laser diodes reduce hardware complexity while maintaining spatial and temporal coherence for precise imaging.
- Compact Raman Laser Multi-Pass Cell Confocal Lens Retro-Lens
Confocal lens pairs and retro-lens assemblies in a multi-pass cell enable high integrated Raman gain at low peak powers while reducing device complexity.
- Distributed Brillouin Sensor Fiber with Negative Dispersion
Negative dispersion in the sensor fiber suppresses nonlinear effects, extending sensing reach.
- Fiber Laser Filter for Reflected Light Damage Suppression
A fiber laser filter blocks maximum gain wavelengths while transmitting signal light to prevent internal damage from reflected light.
