Optical Resonator Shape And Construction TRIZ Cases
- Ionization Gratings for Short-Pulse Laser Temporal Contrast
Intersecting pump beams form a transient ionization grating that diffracts the main pulse while letting pre-pulses pass, improving laser temporal contrast.
- Multi-Wavelength Laser Output Control for Stable Beam Shape
Pulse-width modulation and harmonic output adjustment keep 1064 nm and 532 nm laser beams stable in shape, energy, and treatment use.
- Optical Frequency Scanning Laser for Multi-Channel Angle Ranging
Nonmechanical optical frequency scanning switches channel bands and propagation angles to improve multi-channel distance measurement and noise tolerance.
- Optical Resonator Etalon Layout for Compact Wavelength Control
A perpendicular etalon placed near the output reflector limits wavelength without enlarging the resonator, while suppressing unwanted resonance.
- Frequency-Tripled Solid-State Lasers for UV Annealing Line Beams
Multiple frequency-tripled solid-state lasers are combined into a UV line beam for annealing, cutting excimer cost while preserving pulse energy.
- Blue Laser Frequency Quadrupling at the H-Beta Fraunhofer Line
A Tm:Lu2O3 pulsed laser uses staged frequency quadrupling to reach 486.13 nm with narrow bandwidth and high peak power for underwater sensing.
- Gas Laser Resonator Beam Expander for Stable Exposure Resolution
A convex-concave mirror beam expander stabilizes laser beam width and polarization, improving exposure resolution without fragile line-narrowing optics.
- Silicon-Assisted SOA Array Packaging for Compact FMCW LiDAR
A silicon-assisted SOA and U-turn chip assembly replaces bulky beam-steering optics, shrinking FMCW LiDAR while improving reliability.
- Cr-Doped Mid-IR Laser Oscillator for Low-Noise CEO Locking
Direct diode-pumped Cr-doped mid-IR pulses use spectral broadening and f-2f detection to stabilize CEO with lower noise and less complexity.
- Electro-Optic Prism Wavelength Control in Excimer Lasers
Voltage-driven electro-optic prism steering enables faster, more accurate excimer laser wavelength control to reduce chromatic aberration.
- Isolated Ring Cavity Resonator With Flexure Thermal Isolation
Flexure mounts separate heat-generating optical elements from the baseplate to limit thermal expansion and preserve cavity stability and beam quality.
- T-Shaped Laser Pumping Assembly With Fluorescent TIR Coupling
A fluorescent concentrator couples trapped light into a thin laser medium to raise pump power density, gain, and optical damage tolerance.
