Very early in the history of lasers it was recognized that the high power beam from a ruby laser could perform a variety of practical tasks. It could weld and drill holes easily; enthusiasm for exploitation of these capabilities ran very high. However, it took many years before lasers were employed in a practical sense by industry. The early lasers were not reliable and durable enough. Even though a laser could perform many useful tasks well, it was often unfeasible economically.
