UV spectrometer with laser diodes and laser frequency multiplication |
摘要 |
A laser spectrometer suitable for detecting gas components in a test sample in the ultraviolet range. The measuring laser radiation (2) is sent to a nonlinear crystal (20, 40, 41), which increases the nominal laser frequency to the frequency that corresponds to the absorption wavelength of the measured gas. Tripling of the frequency takes place either after passage of the radiation through a single nonlinear crystal (20), or by mixing a frequency-doubled laser beam with the measuring laser radiation (2) in a common, second nonlinear crystal (41).
