Abstract:
The results are given of the first experiments on laser micromachining of objects by an amplified light beam of specified configuration with simultaneous visual monitoring of the machining process on a screen. A minimum cut width of 2 μ was achieved when machining metallic films deposited on a dielectric substrate. Maximum power densities of 0.1 GW/cm2 (average) and 1 TW/cm2 (peak) were obtained in a focal spot. Measurements of the contrast of the amplified image showed it to vary negligibly, even under conditions of considerable saturation, over a wide range of machining beam powers and to remain close to that obtained when the beam was absent.
