Do laser diodes have to be covered up
The laser diode front facet is extremely sensitive and must be kept free of dust, water and any other kind of contamination. Any contact to the laser front facet will lead to irreversible damage and failure of the laser diode, even if there is no sudden failure. Protecting a laser diode boils down to one core principle: rigorously controlling the electrical current and thermal environment at all times. Because they are exceptionally sensitive to even momentary electrical spikes and reverse voltage, a standard power supply is inadequate and will likely. This application note describes precautions in the use of laser diodes. and that I shouldn't be so keen to rule out all possibilities of forgetting the glasses would also be a relief.
