Application context
Why this design is used
Applications named on this model’s datasheet, expanded with the model’s optical specifications.
Pump source for OPO
FL-1270-CW: 1270 nm emission determines compatible optics, coatings and detectors for Pump source for OPO. The catalogued beam parameter (<1.3) helps predict how the source will focus and propagate through the instrument.
Laser lidar
FL-1270-CW: Laser lidar depends on how optical energy is delivered to the target; 1270 nm emission governs absorption, while pulse energy, duration and repetition rate governs peak intensity and heat deposition.
Interferometry
FL-1270-CW: Interferometry benefits from a stable, focusable source. 1270 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (<1.3) informs waist size and propagation.
System integration
Integration and compatibility
Use these checks to connect FL-1270-CW to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Fiber delivery interface
- Fiber connector: FC/APC, Collimator optional
- 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.
- Thermal management
- Cooled method: Air cooled · 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.
- Beam parameters at the output
- Beam diameter (mm): 4±1 (Collimator output) · Polarization ratio: Random
- 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.
