Application context
Applications named on this model’s datasheet, expanded with the model’s optical specifications.
FL-1940-CW: 1940 nm emission determines compatible optics, coatings and detectors for Pump for medical surgery. The catalogued beam parameter (<1.5) helps predict how the source will focus and propagate through the instrument.
FL-1940-CW: 1940 nm emission determines compatible optics, coatings and detectors for Plastic welding. The catalogued beam parameter (<1.5) helps predict how the source will focus and propagate through the instrument.
FL-1940-CW: 1940 nm emission determines compatible optics, coatings and detectors for Cutting. The catalogued beam parameter (<1.5) helps predict how the source will focus and propagate through the instrument.
FL-1940-CW: Non-metal materials processing depends on how optical energy is delivered to the target; 1940 nm emission governs absorption, while pulse energy, duration and repetition rate governs peak intensity and heat deposition.

Technical FAQ
Fiber connector: Collimator. Match the listed connector and fiber mode exactly; SMA905, FC/PC and FC/APC are not interchangeable, and a single-mode launch requires mode-field as well as numerical-aperture matching.
Cooled method: Air cooled (≤30W) / Water cooled (>30W) · Operating temperature (℃): 15-35. Provide the stated cooling method and keep the laser-head base thermally coupled; temperature drift moves wavelength, output power and beam pointing.
M2: <1.5 · Beam diameter (mm): ~7mm (Collimator outptut). Size the downstream optics from the stated beam diameter and divergence rather than from the aperture of the housing, and confirm the polarisation state before specifying isolators or polarising optics.
Share wavelength, operating mode, output power or pulse energy, linewidth or pulse width, delivery, control, and safety requirements and we will qualify the matching configuration and lead time.

Choosing a laser
Which specifications decide the experiment, and which ones cost money without changing the result.
PhotonicsLinewidth, spectral width, RIN, M², and coherence length answer five different questions. Translate each into the units your experiment is designed in — and learn which ones not to pay for.

PhotonicsSingle-mode fiber does not preserve polarization. Pin the state, erase it with a scrambler, or maintain it in PM fiber — which one your measurement needs, and the response time and extinction ratio that decide it.
