Paper Abstract

A construction of a low-cost wavemeter based on the transmittance of a colored glass filter is presented. The device is tested with a free running 654 nm diode laser and its uncertainty is estimated to be about 1 cm-1, which originates mainly from the mode structure of the diode laser. Along with wavelength measurements, the device can be used also for analysis of the mode structure of free running diode lasers.
