WARNING
CAUTION

For Class 3B lasers
The built-in laser diode is active whenever the instrument is powered on,
therefore disabling the output is not sufficient to establish eye and skin
safe conditions.
Protect your extra-high power tunable laser from damage:
• Clean the instrument's output connector and all interfaces of attached
fibers and termination devices to avoid burning-in dust and other
residue!
• Do not leave plastic caps on the output connector or on the end of a
connected fiber when you activate the laser – you risk damaging the
connector surface with deposit from hot plastic!
• Make sure the optical path is terminated properly and confirm that the
termination can cope with an optical power level of over +18.5 dBm or
70 mW!
• Use a metal cap to cover the laser outputs when open. Terminate
open patchcord ends with a commercially available "fiber optic light
trap".
