Abstract: A system and method for pre-aligning a light beam in a spectroscopic measuring device such as a pump-probe device prior to conducting a measurement procedure is provided, which eliminates the need for monitoring or modification of the beam trajectory through adjustments of elements transmitting the beam (e.g., mirrors) over the course of a measurement process.

Abstract: A system and method for aligning a light beam in a spectroscopic measuring device such as a pump-probe device is provided. The system and method comprise a first motorized mirror (66b) positioned to receive and transmit a light beam (60a); a second motorized mirror (66c) positioned relative to the first mirror to receive the light beam from the first mirror and transmit the light beam to a delay line (64); a third mirror (78) positioned to receive the light beam from the delay line and transmit said light beam to a detector (80); and a computer-based processor (82) in communication with the detector and the first and second mirrors, the processor configured to a) receive and process data relating to the light beam from the detector, and b) cause movement of the first and second mirrors to change an angle of the mirrors based on the data relating to the light beam.
