Hello, I am interested in the Fiber-Coupled Laser Sources: NIR with 980 nm wavelength. it stated that the Minimum Full Output Power is 13.0 mW. What is the maximum power? Does this laser have internal modulation or do we need to modulate it externally? Best regards, Rawan

Hello Rawan, thanks for reaching out to Thorlabs. For S1FC980, we guarantee at least a full output power of 13.0mW or more, typically the max full output can be a little higher than this, though it varies slightly between units. The unit can be tuned from 0mW to max output. The power can be adjusted from 0mW to the full output power, using either the control knob or the analog modulation port. This laser does not have an internal frequency generator, but you can apply external DC or sine signals up to 5kHz to modulate the output. I've reached out directly to discuss this application further.
Ben Garber  (posted 2020-06-26 19:35:43.303)
I was wondering what constitutes small-signal for the modulation bandwidth of the S1FC980. Specifically, for sine wave modulation, what kind of depth could we expect at 15kHz?
asundararaj  (posted 2020-07-07 04:41:55.0)
Thank you for contacting Thorlabs. The small signal modulation amplitude is about 100 mV at 30 kHz, which is about a 2% modulation depth. I have contacted you directly about the performance at 15 kHz.

Single Mode Fiber-Coupled Laser Sources

  • Six Wavelengths Available: 785 to 1550 nm
  • Minimum Full Output Powers of Up to 25.0 mW
  • Fiber Patch Cables Sold Separately

These Single Mode Fiber-Coupled Laser Sources conveniently package a pigtailed Fabry-Perot laser diode and current controller into a single benchtop unit. The Fabry-Perot laser diode inside each unit is pigtailed to a single mode fiber that is terminated at an FC/PC bulkhead (wide and narrow key compatible) attached to the front panel of the unit. Thorlabs offers single mode fiber optic patch cables for connecting to the bulkhead on the front panel. To minimize losses, we recommend using a fiber patch cable that is the same fiber type as the fiber-pigtailed laser; refer to the Specs tab for the internal fiber type used for the pigtail. Additionally, to reduce noise from back reflections, we recommend that a hybrid FC/PC to FC/APC cable be used with the FC/PC end connected to the laser source.

Also found on the front panel is a display that shows the output power in mW, an on/off key, an enable button, and a knob to adjust the laser power. The back panel includes an input that allows the laser diode drive current to be controlled via an external DC or sine wave voltage source and a remote interlock input.

Note: The laser must be off when connecting or disconnecting fibers from the device, particularly for power levels above 10 mW.

S1FC1310PM Shown with PM1300-XP
Polarization-Maintaining Patch Cable
  • Three Wavelengths Available: 785 nm, 1310 nm, and 1550 nm
  • Minimum Full Output Powers of Up to 6.25 mW
  • Fiber Patch Cables Sold Separately
  • Slow Axis of the PM Fiber Aligned to the Narrow Key of the FC/PC Bulkhead Connector

These Polarization-Maintaining Fiber-Coupled Laser Sources package a pigtailed Fabry-Perot laser diode inside each benchtop unit. The laser diode is pigtailed to a single mode PM fiber that is terminated at an FC/PC bulkhead attached to the front panel of the unit. During the pigtailing process, the fiber alignment is actively maintained so that the polarization axis of the laser diode is aligned with the slow-axis of the PM fiber. In addition, the slow-axis of the PM fiber is aligned to the narrow key of the FC/PC bulkhead connector on the front panel of the benchtop unit. Thorlabs offers polarization-maintaining fiber optic patch cables for connecting to the bulkhead on the front panel. To minimize losses, we recommend using a fiber patch cable that is the same fiber type as the fiber-pigtailed laser; refer to the Specs tab for the internal fiber type used for the pigtail. Additionally, to reduce noise from back reflections, we recommend that a hybrid FC/PC to FC/APC cable be used with the FC/PC end connected to the laser source.

Also found on the front panel is a display that shows the output power in mW, an on / off key, an enable button, and a knob to adjust the laser power. The back panel includes an input that allows the laser diode drive current to be controlled via an external voltage source and a remote interlock input.
