OWNERS MANUAL | Cobolt 06-01 Series | D0136-P October 2023 06-DPL Which modulation type to use? The Cobolt 06-DPL has two different modulation types: digital and analog. These two modes aim to cover most applications the user may have. • Digital modulation allows for modulation speeds of up to 50 kHz (532 nm), 5 kHZ (553 nm), or 10 kHz (561 nm) with a rise time of under 6, 60 and 30 µs respectively. - Page 39 OWNERS MANUAL | Cobolt 06-01 Series | D0136-P October 2023 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.
- Page 40 OWNERS MANUAL | Cobolt 06-01 Series | D0136-P October 2023 Settings Optimization in modulation mode Cobolt Monitor™ software allows the user to optimize the laser performance while in modulation mode. During manufacturing the 06-DPLs settings are optimized for digital modulation at 1 kHz and a 50% duty cycle. Examples of the effect of modulation frequency on pulse shape.
