• Polarization-Maintaining Pigtail
• Internal 8° Angle Cleaved Fiber
• Ø9 mm Package
• Custom Pigtails Available Upon Request

This pigtailed laser diode made with polarization-maintaining fiber allows the polarization state of the light emitted from the diode junction to be preserved as it is transmitted through the fiber. The light emitted from the laser diode will be linearly polarized predominantly along an axis parallel to the length of the laser diode junction. Since the laser junction is not one-dimensional, some light is emitted perpendicular to the laser diode junction.

Our high-quality SM pigtail alignment process for laser diodes includes multiple test and inspection points that ensure that the coupling efficiency is maximized. In addition, the input end of the fiber is cleaved at an 8° angle in order to minimize back reflections that can cause the output intensity to fluctuate. Single mode pigtails provide coherent fiber-coupled output from a laser diode. This diode has a Ø9 mm package and a design wavelength of 830 nm.

Note: The reliability of the laser diode/pigtail rapidly declines at higher temperatures. Therefore, for stable output power and wavelength, it is highly recommended that you use a temperature controller with this product.
