Mercury vapor filter technology and ultraviolet laser source for flowfield imaging Conference Paper uri icon

abstract

  • 1997, American Institute of Aeronautics and Astronautics, Inc. We present a narrow spectral passband filter capable of imaging rotational Raman scattering. The mercury vapor based filter has a spectral passband of less that 1 cm and high out-of-band suppression. The filter is coupled with a narrow linewidth ultraviolet laser source. The laser, based on frequency tripling the output of an injection seeded, cavity locked titanium: sapphire resonator achieves in excess of 35 mJ/pulse of tunable single mode light at 250 nm. The filter and laser are used to measure individual lines of pure rotational Raman scattering from room air.
