Semiconductor Laser Optical Device TRIZ Cases
- Optical Frequency Comb Resonance Control for Stable Frequency Switching
Filtered carrier detection guides resonator length or laser frequency feedback to stabilize optical comb output and reduce switching errors.
- Segmented Lighting Optics for Fast Spot-Uniform Distance Sensing
Independent light-emitting sections and beam-shaping optics enable fast switching between spot and uniform irradiation in compact distance sensors.
- Edge Coupler and Deflector Structure for Low-Loss Optical Coupling
A lateral deflector redirects incoming light into a polarization-independent edge coupler to cut optical loss across wider wavelength ranges.
- Surface-Emitting Laser Module With Phase Correction for Fiber Coupling
Phase-corrected coherent lasing units turn high-power surface-emitting beams into a single main lobe for efficient optical fiber pumping.
- Beam Coupling Optics for Dense Laser Beam Combining
A 2D emitter layout with optical units and a cylindrical lens enables dense beam coupling while keeping beam diameter small for laser processing.
- Diode-Pumped Solid-State Laser Beam Shaping for Uniform Thin-Disk Pumping
A twisted beam-shaping optic symmetrizes diode bar beamlets into a uniform flat-top pump, reducing thermal lensing in thin-disk lasers.
- Laser Light Module Protection Circuit for Class 1 Eye Safety
A protection controller cuts laser drive current on current-source failure and controls temperature to keep output within Class 1 eye-safe limits.
- Laser Beam Splitting for Maskless Display Pad Bonding
Diffractive beam splitting targets only display pads and emitters, reducing heat spread, eliminating masks, and improving laser use.
- Fiber Laser Ferrule and Housing for Compact Heat Dissipation
Matching metal ferrules and housing to the fiber improves heat conduction and limits thermal stress in compact short-fiber lasers.
- Yb:YAG Laser Spatial Filtering for Longer OPO Pump Pulses
A spatial filter in a passive Q-switched Yb:YAG laser extends pulse width while preserving single-mode output and reducing OPO crystal damage.
- Laser Irradiation Assembly for Gaussian Fusion Pellet Illumination
Phase-shaped laser beams create a Gaussian-like spot on fusion fuel pellets, improving irradiation uniformity and energy coupling.
- Light Emitter Module Cover Sensing for Crack and Moisture Hazards
Separate conductive traces on the transmissive cover detect cracks and moisture, enabling rapid light-source shutdown to prevent eye and skin hazards.
- Deflector-Edge Coupler Structure for Broadband Optical Coupling
A lateral deflector redirects incoming light toward an edge coupler, improving chiplet optical coupling across wider wavelengths and polarization states.
- Laser Line Generator with Cylindrical Lens and Diffraction Grating
A laser line generator shapes collimated beams into planar patterns using cylindrical lenses and diffraction gratings.
