Laser-ablation absorption spectroscopy: Reviewing an uncommon hyphenation

Jonathan Merten

Summary: This review examines the history and experimental methods of absorption spectroscopy of laser-induced plasma, and discusses its applications in analytical chemistry and plasma diagnostics. Due to the differences between laser-induced plasma and conventional atomic absorption spectroscopy, the assumptions of the Beer-Lambert Law need to be reconsidered.

Burst-mode dual-comb spectroscopy

Yu Zhang et al.

Summary: The study presents a new modality of dual-comb spectroscopy that offers a simplified and powerful approach for time-resolved measurements with increased acquisition rates. By multiplexing each probe pulse into a short train of pulses, a time-resolved series of absorption-based spectroscopic measurements was demonstrated, identifying 22 Nd lines not previously reported. This modification to dual-comb systems enables flexible studying of transient and low-duty-cycle events.

Time-resolved absorption spectroscopic characterization of ultrafast laser-produced plasmas under varying background pressures

S. S. Harilal et al.

Summary: Time-resolved tunable laser absorption spectroscopy is used to characterize the physical properties of ultrafast laser-produced plasmas. Different pressure levels were found to have varying late time physical properties in the plasma. The study also showed that lower state population exists in the early stages of ultrafast laser-produced plasma evolution.
