The input signal should be connected to the BNC connector on the key control box or via the 6-pin Molex connector
on the back of the laser head. The laser is calibrated so that 1.3 V input results in the maximum allowed diode current.
Note that the laser may give more power if a voltage larger than 1 V is used. Although the current is clamped to a safe
current limit to prevent damage, the user must nevertheless avoid overdriving the diode so that it gives more than
the nominal power level. Specifications and diode lifetime are not guaranteed above nominal power, which is stated
on
the manufacturer’s identification label
on the laser head. Measure the input voltage before connecting to the laser
head.
Analog modulation and direct ON/OFF cannot be used simultaneously.
Typical analog modulation pulse shape, 06-DPL output on channel 1 (blue), function generator input on channel 3
(purple) of 0-1 V sinus, 100 Hz.
Modulation mode combinations
In addition to the modulation types described above, the Cobolt 06-DPL can be operated with a combination of
modulation signals.
D Analog
The 06-DPL can be used with hybrid digital + analog modulation. This can be accessed in the Cobolt Monitor
™
software under the Modulation Type option. In this mode, whenever the digital state is on, the laser runs at a power
determined by the analog voltage.
