Introduction In 1916 Albert Einstein postulated the effect of stimulated emission of radiation and thereby laid the theoretical foundations of modern laser technology. However, it was not before 1960 that the first laser, a ruby laser, was built by T.H. Maiman. Today, lasers are widely employed in both civilian and military settings. Examples for civilian applications include CD-players, medica...
Two color laser diagnostics using terahertz laser sources are under development for a high performance operation of the Large Helical Device and for future fusion devices such as ITER. So far, we have achieved high power laser oscillation lines simultaneously oscillating at 57.2 and 47.7 μm by using a twin optically pumped CH(3)OD laser, and confirmed the original function, compensation of mech...
A multi-wavelength laser is demonstrated using a dye-doped cholesteric polymer film whose reflection bandwidth is broadened with several oscillations. Due to the abrupt change of the density of state between oscillation peak and valley, each oscillation functions as a photonic band gap for generating a laser wavelength under the excitation of a pumping laser. As a result, a multiple wavelength ...
