FLS Series
Fixed-wavelength narrow-linewidth semiconductor laser with the power supply and driver integrated in the housing. The emission wavelength is specified at order and can be retuned after purchase.
Technical overview
The FLS is a compact fixed-wavelength diode laser source whose emission wavelength is set to order anywhere in 1180-1370 nm or 1400-1680 nm, to an accuracy of +/-0.2 nm. Typical linewidth is 30 kHz (minimum 10 kHz) with typical RIN of -150 dB/Hz and output power of +10 dBm or more, on polarization-maintaining fiber with a selectable optical connector. Power supply and driver are integrated in the 141 x 137 x 71 housing, controlled over a serial interface, and the manufacturer offers customization including multi-channel and multi-wavelength builds.
