Propagation of two‐dimensional and quasi‐one‐dimensional Laser Supported Detonation (LSD) waves driven by a line‐focusing laser beam was investigated using the shadowgraph method. As a result, fractional laser absorption during the LSD regime for 2D and quasi‐1D cases was 68% and 81%, respectively, which was lower than that of three‐dimensional LSD wave driven by a point‐focusing beam (typically 90%.) However, the blast wave energy efficiency was found proportional to the fractional absorption. Besides, the LSD threshold intensity was apparently lowered in the quasi‐1D case due to the momentum confinement effect. Comparison with the quasi‐1D simulation considering the real gas effects suggests that non‐equilibrium effects and radiation loss should be playing an important role in the energy conversion process in the LSD regime.
