SKU: SUPL
The SUPL is a single-mode supercontinuum ASE source providing continuous emission from 450 to 2300 nm, with up to 7 W average output power and power stability better than 0.5% RMS. The system uses a 1060 nm pulsed fiber laser to pump a photonic crystal fiber (PCF), producing a spatially coherent, diffraction-limited beam across the entire spectral range. The SUPL delivers highly stable linear polarization, featuring an extinction ratio of up to 35 dB with minimal sensitivity to time or temperature variations, making it an ideal polarized broadband light source for demanding applications. Available as a ready-to-use benchtop unit, the SUPL offers two repetition-rate configurations: 100 kHz and 4 MHz with pulse duration of 100ns and 10ns, respectively. Shorter pulses generate lighter in the blue spectral. Both output power and repetition rate are user-adjustable via front-panel controls or a USB-based GUI. A TTL BNC output is provided for synchronization with external instrumentation. In its standard configuration, the SUPL provides free-space output from a PCF terminated with a fused glass core endface, ensuring damage resistance while preserving single-mode propagation. Due to the significant mode-field mismatch between PCF and conventional optical fibers, direct connectorization typically results in coupling losses exceeding 10 dB. To mitigate this, mode-field-adapter splicing is available, along with a range of optional connectorized fiber outputs for streamlined system integration. Note that wavelength coverage may be limited by the selected single-mode fiber, while use of multimode fibers may affect mode characteristics. For applications sensitive to back reflections, an optional output isolator is available to ensure optimal operational stability.
