Optical Resonator Shape And Construction TRIZ Cases
- Femtosecond Fiber Laser Pulse Picking Without Optical Shutters
By removing the optical shutter and using pulse picking plus continuous-wave protection, this laser setup cuts size and power while switching faster.
- Line-Narrowing Laser Wavefront Control for Stable Spectral Width
Feedback wavefront adjustment keeps excimer laser spectral width narrow and stable as pulse repetition frequency changes.
- Birefringent Laser Cavity Control for Low-Noise Frequency Combs
A birefringent element and polarizer in the laser cavity suppress soliton self-frequency shift, cutting RIN-driven CEO phase noise and linewidth.
- Double-Pass Optical Fibre Amplifier Layout for Reflection Loss Control
AOM face angles and downstream fibre transit timing suppress parasitic reflections and overmodulation in double-pass optical fibre amplifiers.
- Mid-Infrared Fiber Laser Architecture for Long-Wavelength Power Gain
A staged fiber and nonlinear-fiber chain extends mid-infrared output beyond 5 μm while boosting power in the later spectral band.
- Laser Oscillator Space Filter Structure for Pulse Noise Attenuation
A support member with a beam-narrow opening acts as a space filter to attenuate long-wavelength pulse noise and improve PCB drilling quality.
