Wavelength-modulation spectroscopy using a frequency-doubled current-modulated diode laser
We have studied atomic absorption in an argon discharge by wavelength-modulation spectroscopy with a frequency-doubled diode laser. The tunable wavelength-modulated radiation at 430 nm was generated by frequency doubling a current-modulated 860-nm diode laser in a KNbO3 crystal. 2f-, 4f- and 6f-harm...
