A high-temporal resolution, broadband pulse shaping network is realized using a 2-D VIPA-grating dispersive element pair, with a programmable SLM at a common Fourier transform plane. True wavefront reversal (“time reversal”) is realized using a self-starting RA-PCM, which compensates for system path distortions, misalignment, beam wander, vibrations and optical aberrations. Upon reverse transit through the system, the RA-PCM wavefront matches the set of virtual images emerging from the VIPA. The RA-PCM is a self-starting, low-power device, without frequency shifts, doesn't require pump beams and/or the need for high-intensity stimulated scattering threshold conditions to be met. Polarization decoupling enables the RA-PCM to compensate for optical distortions, while enabling the SLM to generate real time Fourier phase masks for programmable pulse shaping."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Programmable pulse shaper using a VIPA-grating pair integrated with a spatial light modulator and a retro-array phase-conjugate mirror","description":"A diffraction-limited, programmable pulse shaping network using a virtually integrated phased array (VIPA)-grating pair, integrated with a 2-d transmissive phase-only spatial light modulator (SLM) and","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11953776","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
