More Information
Summary:A wavemeter for monitoring a wavelength of emission from a tunable laser includes a spectrometer disposed within a housing having a controlled pressure, and a temperature sensor and/or a pressure sensor for sensing the temperature and/or pressure, respectively, within the housing. The temperature and/or pressure are controlled such that they have relative values, and materials are selected, each for substantially minimizing temperature sensitivity of the spectrometer, such as for providing a temperature sensitivity of the spectrometer within ±0.1 pm/°K.
