These diode lasers are compact single frequency light sources with a sub-MHz line width (in cw mode). A modulation input is possible on demand. Available wavelengths for standard products are in the range of 1530nm-1565nm (other wavelength can be discussed).
The output power in the range of 8-15mW may be post-amplified by an integrated EDFA. Also wavelength multiplexing is available for customized versions.
The narrowband diode lasers can be used in many test and measurement applications, in particular all typical and advanced spectroscopic measurements. The mode-hop free tuning range is typically 20 GHz and the total tuning range up to 100 GHz (0,8nm).
