The finely polished ends of the rod were silvered; one end completely, the other only partially. Since the ruby is in solid form therefore there is no chance of wasting material of active medium. Ruby lasers produce pulses of coherent visible light at a wavelength of 694.3 nm, which is a deep red color. The active laser medium (laser gain/amplification medium) is a synthetic ruby rod that is energized through optical pumping, typically by a xenon flashtube. In many cases, this curve is close to linear, so that the specification of the slope efficiency as … [3][4], One of the first applications for the ruby laser was in rangefinding. [8] Many non-destructive testing labs use ruby lasers to create holograms of large objects such as aircraft tires to look for weaknesses in the lining. Electrons in this level have an average life time of about 5m.s before they fall to ground state. a laser based on the solid-state laser material Ruby. A. Morozov & V. P. Khyuppenen Journal of Applied Spectroscopy volume 21, pages 1454 – … The whole assembly is kept in the glass tube.
