LE-0200 Ruby Laser

In 1960 T. Maiman realized the first laser, the Ruby laser, which started a tremendous and ongoing development of laser sciences and optical technologies. Looking back into laser history, Maiman's famous Ruby laser initiated a fascinating development, which also led to the invention of the powerful tiny diode laser used here to pump the Ruby laser, allowing now a compact and low-cost laser setup, well suited for demonstration and education purposes. This experimental Ruby laser allows the study of the observation of the fluorescence and laser spectrum with oscillations of both the R lines. The dynamic of the three level laser system is studied by modulating the pump diode laser.
It seems so, as if with this system "The Laser Odyssey" will find its happy end.
