Description
A compact laser wavelength measurement device, with on-unit display, and ethernet/USB connectivity standard. Our device clearly reveals multimode laser operation (1), making it particularly suitable for use with external cavity diode lasers and atom cooling and trapping experiments. At prices so low (US$4050 including shipping) you can afford to put a wavemeter on every laser in your lab, so you know if your laser is unlocked or multimoding. Now in its sixth generation.
Sample of spectrum for an external cavity diode laser operating in multiple longitudinal modes of the semiconductor diode cavity. Inset detail shows clear separation of the two diode modes.
