New CH3OH laser lines pumped with a fine-tuned high-power CO2-TEA laser

Joule-level pulses from an etalon tuned CO₂-TEA laser with an ～ 4GHz intraline tuning range have been used to pump a large number of new CH₃OH FIR laser lines. FIR wavelength measurements, pump laser offsets which produced FIR laser lines and pump laser offsets at which CH₃OH absorption lines were observed are reported. Identifications are proposed for most of the absorption lines, and an attempt to identify the FIR laser lines is described.
