Abstract :
Multi-line far-infrared (FIR) gas lasers from a single laser cavity have been development in order to apply ITER diagnostics. By using two pump CO2 lasers with different wavelength and mixed gas of CH3OH and CH3OD, we succeeded in the simultaneous oscillations of three-color FIR lasers of 48, 57, 119 μm in wavelength.
