Computer controlled IR spectrometer using a color center laser

A high resolution IR spectrometer for the
2.2-3.3\mu
m range has been developed using a computer controlled CW color center laser. Computer control makes possible single-frequency scans of up to 100 cm
^-1
with a resolution determined by the cavity mode spacing (250 MHz) and continuous high resolution scans (linewidth below 1 MHz) over 1 cm
^-1
ranges. The laser spectrometer has been tested on the NO overtone band at 2.68 μm.
