  • Custom Wavelengths Available
  • Single Mode FC/PC Fiber Interface
  • Stable, Low Noise, Constant Power Output
  • Interlock Input

The S1FC Series 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 2.1 mm key compatible) attached to the front panel of the unit. The specific fiber types used internally for the pigtail are listed in the Specs tab. For connection to external devices, Thorlabs offers single mode fiber optic patch cables.

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 (DC or sine wave inputs accepted) and a remote interlock input. All of our fiber-pigtailed lasers utilize an angled fiber ferrule at the internal laser/fiber launch point to minimize reflections back into the laser diode, thereby increasing the stability of the laser diode's output.

For applications using a 635 nm or 1550 nm source, Thorlabs also offers a compact fiber-coupled laser source with a USB interface. For a polarized output, laser sources that incorporate polarization-maintaining fiber are also available for many of the same output wavelengths. For optogenetics applications, Thorlabs offers a 473 nm benchtop laser source that incorporates multimode fiber.

 

Temperature-Controlled Laser Sources: FP Laser Diode

 

S3FC Fabry-Perot Series Features

  • Standard Available Wavelengths: 405 nm, 473 nm, and 488 nm
  • Custom Wavelengths Available
  • Thermo-Electric Temperature Stabilization
  • Adjustable Temperature Set Point
  • Adjustable Power
  • Interlock Input

The S3FC series of single channel benchtop lasers have an integrated TEC element that is used to stabilize the temperature of the FP laser diode, which in turn stabilizes the output power and wavelength of the laser diode for a given drive current. The FP laser diode is pigtailed to a single mode fiber that is terminated at an FC/PC bulkhead connector (wide 2.1 mm key compatible) on the front panel. Also found on the front panel is a display that selectably shows either the output power in mW or the temperature in °C, a on / off key, an enable button, a knob to adjust the laser power (drive current), and a knob to adjust the temperature (TEC current). 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. All of our fiber pigtailed lasers utilize an angled fiber ferrule at the internal laser/fiber launch point to minimize reflections back into the laser diode, thereby increasing the stability of the laser diode's output. For applications that require several laser sources, consider the temperature stabilized four channel fiber coupled laser source.


Temperature-Controlled Laser Sources: DFB Laser Diode

 

S3FC DFB Series Features

  • Two Wavelengths Available: 1310 nm and 1550 nm
  • Narrow Spectral Linewidths: <0.6 nm
  • Thermo-Electric Temperature Stabilization
  • 40 dB Optical Isolation
  • Adjustable Temperature Set Point
  • Adjustable Power
  • Interlock Input

The S3FC Series Fiber Coupled Laser Sources feature a narrow linewidth DFB laser diode and a 40 dB optical isolator to eliminate back reflections and frequency jitter. The S3FC Series incorporates an integrated temperature control system for increased wavelength and power stability. The diode temperature and output power can be adjusted using the two front panel adjustment knobs, which ensures that the DFB laser diode can be tuned to match the laser cavity. Also found on the front panel is a display that selectably shows either the output power in mW or the temperature in °C, a on / off key, an enable button, and the FC/PC bulkhead connector (wide 2.1 mm key compatible). 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.
