Request InfoID QuantiqueThe id300 laser source from id Quantique SA generates short laser pulses at wavelengths of 780, 850, 1310 or 1550 nm. It is designed to work with the id200 single-photon-detection and -counting modules at telecommunications wavelengths. Based on a VCSEL (for 850 nm) or a Fabry-Perot laser diode (for the other wavelengths), the source is triggered externally to produce subnanosecond pulses with a repetition rate ranging from DC to 500 MHz. It has a pulse duration of 300 ps, a peak power of 1 mW and a typical spectral width (FWHM) of 7 nm. Polarization-maintaining fiber is optional.
