Transient Absorption by Multiple Pass(TrAMP).

(a) Experimental scheme of TrAMP system.The Modulated pump beam and the probe beam are made to pass through the sample several times within the misaligned cavity made of the two curved mirrors .The sample is placed at the focus of the cavity. A set of filters and a monochromator are used to remove the pump before sending the probe beam to the detection system. (b) TrAMP kinetics collected by increasing the number of passes. The sample is 15 nm film of P3HT (OD = 0.1), the pump is at 400 nm and the probe at 680 nm.
