This fiber laser line generator is pre-aligned to produce a diverging line of light at 633 nm from an FC/PC-terminated single mode fiber. Because this fiber component has no movable parts, it is compact and easy to integrate into an existing setup. The cylindrical lens within the package collimates the output of a single mode fiber in one dimension, resulting in a diverging line output with a Gaussian intensity profile. The line generator produces a theoretical 23° full-angle divergence for light at the design wavelength and a fiber with a mode field diameter (MFD) of 4.3 µm. The actual divergence angle of a laser line will depend on the fiber NA and the wavelength of the light; please see the Divergence Info tab for more detail.
The cylindrical lens within this line generator has an AR coating on both sides that minimizes surface reflections from 350 nm to 700 nm. For some applications, this line generator can be used at wavelengths within the AR coating range other than the design wavelength. Please note that this package is not vacuum compatible and that the operating temperature of the line generator is -40 °C to 93 °C. Line generators with custom alignment, operating temperature, or vacuum compatibility are available by contacting Technical Support.
We recommend using this line generator with our AR-coated single mode fiber optic patch cables. These cables feature an antireflective coating on one fiber end for increased transmission and improved return loss at the fiber-to-free-space interface. Alternatively, our large selection of standard single mode fiber patch cables can also be used with this line generator. We do not recommend the use of multimode patch cables. Our S1FC635 Benchtop Fiber-Coupled Laser and KLS635 K-Cube™ Laser are ideal light sources for use with this component. The laser-induced damage threshold of a system using this line generator with a single mode fiber will typically be limited by the fiber.
The stainless steel housing for this line generator package is unthreaded and has an 11 mm diameter. An engraved line on the side of the housing indicates the orientation of the laser line generated by the package. To mount the line generator package, we recommend using one of our fixed or kinematic collimator mounting adapters for unthreaded Ø11 mm components, which are available with unthreaded 1/2" and 1" diameters or external SM1 (1.035"-40) threads.
For applications requiring a flat-top laser line profile, consider our line of Powell lenses.

The fiber-coupled line generation package includes a cylindrical lens that collimates the output of a single mode fiber in one dimension. This results in a divergent line output with a Gaussian intensity profile. When used with light at 633 nm and a fiber with a mode field diameter (MFD) of 4.3 µm, the 1/e2 power full angle divergence of the line is 15.2°. With these parameters, the length of the line (defined as containing either 1-1/e2 or 99% of the optical power) is given at five distances in the table to the right. The length of the line containing 99% of the optical power is 1.52X the length of the line containing 1-1/e2 of the optical power.
If a different single mode fiber is used with this line generator, the divergence angle of the laser line will differ. More specifically, the 1/e2 divergence angle can be calculated from the numerical aperture (NA) of the fiber, according to equation:
