Colleagues- I'm building a portable LIF spectrometer for atomic lanthanide spectroscopy in the 400-420 nm region. Two lasers that seem interesting are the Toptica DL-100 and the Sacher Lynx. Both lasers are external cavity with a Littrow grating output coupler. Any comments, good or bad, regarding either of these companies or on the performance and reliability of these lasers are invited. Thanks much. -Michael ______________________________________ Michael D.
