06-MLD Modulation
There are three ways of modulating the 06-MLD (digital, analog, and on/off modulation), the simplest of which
is the on/off modulation feature, which requires no data connection to the laser. For a detailed guide to
operating the laser in modulation modes see section 6 : Modulation mode operation.
