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.
LE-0200 Ruby laser with hemi-spheric cavityA. Semi-centric cavity The radiation of the diode laser with a wavelength of 405 nm is collimated and focused into the Ruby crystal. The resonator (A) consists out of a flat mirror (Mirror 1) and a spherical mirror (Mirror M2) and forms a semi-concentric cavity. The Ruby crystal is placed close to the flat mirror. The entire laser operates at room temperature and the Ruby crystal does not need to be cooled extra.
LE-0200 Ruby laser with concentric cavityB. Concentric Cavity The concentric cavity consists out of a resonator with two spherical mirror forming a concentric cavity. The Ruby crystal is placed in the middle of both mirrors. The pump radiation if focused into the center of the Ruby crystal.
