🔦 Chirped-Pulse Amplification: Stretch, Gain and Compress (2D chain view)

2D chain view of chirped-pulse amplification: a femtosecond seed pulse is stretched by a grating pair, amplified in a crystal with gain saturation and compressed again. Set pulse energy, duration, beam radius, repetition rate, stretched duration, compressor throughput and seed energy and watch the peak power, fluence, B-integral and required gain. Same pulse-energy, power and fluence relations as the 3D page, with four in-page numerical checks.
