Tunable, narrow-bandwidth (<200-MHz), ~215-nm radiation was produced by frequency quadrupling the ~860-nm output of a high-power, pulsed GaAlAs tapered amplifier seeded by an external-cavity diode laser. Pulsing the amplifier increased the 860 nm→215 nm conversion efficiency by 2 orders of magnitude with respect to cw operation. Detection of nitric oxide and sulfur dioxide by high-resolution absorption spectroscopy was demonstrated.

  2. For example, the integral cross section of NO at 296 K is 1.3×10-19cm-1 /(molcm-2) at ~6.2mm (Ref.) and 1.8×10-17cm-1 /(molcm-2) at ~215 nm (Ref.); the corresponding low-pressure (Doppler-broadened) peak absorption cross sections are 3.0×10-17cm2/ mol and 1.7×10-16cm2/ mol, respectively.
