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
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.
