The threshold for eye damage at 1550nm and 1310nm is 100mW/cm2.  Damage from light at these wavelengths is mostly to the cornea, rather than the retina, which means it will heal.  Aligning a fiber will not cause damage, but looking directly into a connector while the laser is on very well may because the intensity is so high.

Check the UCSB laser safety manual for guidelines on choosing appropriate goggles for your experiment. In general, there is no need to worry if the power is below:

  • 200mW at 1550nm
  • 10mW at 1310nm
  • 1mW at 1000nm

For higher optical powers, or shorter wavelengths, consult the laser safety manual and UCSB's laser safety officer.
