An ultralow-noise, 5-mW diode laser system with a circular collimated beam has been launched by Coherent Photonics Group, Auburn Div. The ULN series displays rms noise figures of 0.06% or less for detector bandwidths <10 MHz, emits at 635 (+5) nm and produces output powers from 4 to 25 mW. The laser requires no warm-up period and exhibits no mode hopping. It can replace HeNe lasers in applications such as biomedical instrumentation, flow cytometry, particle measurement and fluorescence spectroscopy. Elliptical beam shapes and OEM versions are available.
