Laser Using Scattering Effects TRIZ Cases
- Active-Doped Optical Fiber Core Structure for Raman Suppression
A radially graded doped core suppresses stimulated Raman scattering and higher modes while preserving basic-mode amplification and beam quality.
- Gas-Filled Optical Switch for Residual Pump Beam Absorption
A gas-filled blocker uses optical breakdown and optional electron-beam excitation to absorb residual high-fluence pump pulses and protect seed optics.
- White Laser Fiber Source With Red LED CRI Boosting
A red LED is merged with phosphor-converted white laser light to raise CRI and lower color temperature without major lumen loss.
- Brillouin Cytometry Imaging for Parallel Subcellular Cell Mapping
Parallel Brillouin imaging with VIPA optics and microfluidics captures subcellular mechanical properties faster without point-by-point scanning.
- SBS Ring Resonator FSR Detuning for Narrower Laser Linewidth
By misaligning ring resonator FSR from the SBS gain peak, this case cuts linewidth and frequency pulling while preserving lasing gain.
- Fiber Bragg Grating Protection Against SRS in Fiber Lasers
A fiber Bragg grating reflects unwanted SRS wavelengths away from combiners and pump modules, enabling higher-power fiber laser operation.
- Hybrid Er-Yb Optical Fiber Structure for L-Band Pump Conversion
A hybrid Er-Yb fiber uses dual active regions to absorb multimode 915 nm pump light, suppress C-band ASE, and improve L-band amplification.
- Booster SOA Light Source for Raman Pump RIN and Ripple Suppression
An optimized booster SOA uses controlled nL and drive current to suppress RIN transfer and ripple while maintaining high-output Raman pumping.
