Dual-beam multipass cell compression for time-resolved femtosecond spectroscopy setups [PDF]

EPJ Web of Conferences
We present a dual-beam single multi-pass cell compressor designed for applications in time-resolved pump-probe spectroscopy. A single MPC simultaneously compresses two beams with different pulse energies to the same pulse duration, allowing for ...
