Chirped-pulse amplification stretches a short optical pulse, amplifies it at lower instantaneous intensity, then recompresses it. This installation depicts the concept, not a design for constructing or operating a laser.
Equations: Eγ = hc/λ; Pavg = Epulse × f; illustrative Pscale = Epulse/τ; Nγ = Epulse/Eγ.
Real features: grating-based dispersion control, optical mounts, vacuum compressor, diagnostic instruments. Reconstructions: component layout, frame dimensions, gain head casing, controls. Simplifications: rays and light markers are not to scale; pulse shape, dispersion and losses are omitted. Speculation: decorative enclosure pattern and service routing.
Safety: the exhibit is educational. Real high-power laser operation requires engineered containment and specialist procedures.
Illustrative design, not affiliated with any real institution or manufacturer.
