Thorlabs' LaserPort mounts either a 5.6 mm or a 9 mm customer-supplied laser diode and collimates the laser's emitted light. It offers 5-axis (X, Y, Z, Pitch, and Yaw) adjustment of an aspheric lens relative to a laser diode, allowing the user to adjust the lens for optimum collimation performance. As the LaserPort does not offer TEC control, dissipating heat from the diode is essential for stable power and wavelength output. To accomplish this and to electrically insulate the diode, the LaserPort features a ceramic mounting seat for the diode. To drive the laser diode, we suggest using our SR9 cables; however this configuration will provide an electrical connection only, not strain relief. These cables are designed to accommodate various pin configurations and can be easily integrated with our Laser Diode Current Controllers.
Temporary Fiber Pigtail
The highly-stable 5-axis adjustment, combined with the thermal properties of the mount, provides the LaserPort with excellent stability characteristics. As can be seen at the top right of this webpage, the LaserPort can be paired with a FiberPort on a FiberBench for fiber coupling applications. Depending on the divergence angle of the laser diode, a diode can be coupled into single mode fiber with better than 60% efficiency. This essentially creates a temporary fiber pigtail where the laser diode can be easily swapped. As a testament to this setup's stability, our tests have shown initial coupling efficiency to single mode fiber of 62% only decreasing to 58% over a 7 day period.
