Could you please lost the safety class of your lasers. Due to the significant ASE background, a bandpass filter should be used for precision measurements. What is the make and type of this interlock connector? This can: Factory packaging protects the HeNe lasers from shocks and vibrations during shipping, but end users directly handle the bare laser housing. In extreme cases, shock and vibrations can shatter or fracture glass components internal to the laser. We expect the power to degrade by 1-2% per year, and have a 1-year warranty. Dir Sirs, Never apply a bending force to the laser housing. We'd like to separate the output mirror of a HeNe laser, for use in an undergrad lab experiment to measure the speed of light (if you're interested, it's described in "Measuring the speed of light using beating longitudinal modes in an open-cavity HeNe laser", Am. Alternatively, the HCL2 FiberPort Adapter allows a FiberPort coupler to be attached directly to the front of the laser, as shown to the right.
