Modulation mode operation

In this section the different ways to control the emission of a laser in modulation mode operation will be

discussed in detail. Cobolt 06-01 Series laser will not operate in a digital or analog modulation mode until that

mode is enabled, either in the Cobolt Monitor™ software or via the commands given in section

Communication commands

. 06-MLDs additionally offer ON/OFF modulation, which will be automatically

enabled when a signal is provided to the ON/OFF modulation input but can also be controlled in the Cobolt

Monitor™ software

. O

N/OFF modulation is activated automatically when connected. Modulation mode

settings will be saved and remain enabled or disabled when powering the laser on and off.

.

Cobolt

Monitor™ software windows showing the location of modulation mode functions described in this section.
