    This instrument must not be operated in an explosion endangered environment. LASER WARNING The FSL1550 is a Class IV laser. Avoid Eye or Skin Exposure to Direct or Scattered Radiation. LASER WARNING Always wear appropriate laser safety eyewear during laser setup and operation.
  • Page 6 CLASS 4 LASER PRODUCT Class IV lasers such as the FSL1550 may cause damage to the skin, and also to the eye, even from the viewing of diffuse reflections. These hazards may also apply to indirect or non-specular reflections of the beam, even from apparently matte surfaces.
  • Page 7 1.55 µm Femtosecond Fiber Laser Chapter 2: Safety Mobile telephones, cellular phones, or other radio transmitters should not to be used within the range of three meters of this unit since the electromagnetic field intensity may exceed the maximum allowed disturbance values according to EN50082-1.

  • Page 8: Chapter 3 Description

    3.1. Introduction Thorlabs’ FSL1550 Femtosecond Fiber Laser emits <50 fs pulses with a center wavelength of 1.55 µm at a 100 MHz repetition rate. This fiber laser is based upon an oscillator-amplifier combination that uses only polarization- maintaining fiber, yielding reliable turn-key operation and exceptional long-term reliability. The FSL1550 has a collimated free-space output with a 2.2 mm beam diameter.

  • Page 9: Chapter 4 Setup And Operation

    Chapter 4 4.1. Environmental Requirements The FSL1550 should be operated under controlled conditions to achieve stable performance. 4.1.1. Temperature Range For any laser, the ambient temperature must be well controlled. The ambient temperature of the lab environment should be in the 17 °C - 25 °C range, and should not change by more than 3 °C over any 24 hour period.

Please note that the oscillator status should always show “OSC OK” status. If an oscillator error status is displayed, please contact Technical Support. The interlock circuit in the system should be closed by shorting the BNC connector on the back panel either through a BNC short plug-in connector or a remote interlock circuit.
