The Cobolt 06-01 Series lasers consist of high-performance fixed wavelength laser modules; modulated laser diodes (MLD) and diode pumped lasers (DPL) cover a spectral range between 375 nm and 975 nm. -
Page 6: Safety
Safety General All Cobolt 06-01 Series lasers are Class IIIB (CDRH), Class 3B (IEC) laser products which emit less than 500 mW of laser radiation within the visible spectrum. The residual emission does not exceed Laser Class 1. Eye and skin exposure to direct or reflected laser light is hazardous and may be extremely harmful. Always wear eye protection appropriate to the beam wavelength and intensity. - Page 7 OWNERS MANUAL | Cobolt 08-01 Series | D0141-K SEPTEMBER 2020 Accessible Emission The table below describes the irradiance in W/cm and appropriate level of eye protection in terms of optical density (OD) for each product line.

OWNERS MANUAL | Cobolt 08-01 Series | D0141-K SEPTEMBER 2020 06-MLD Which modulation type to use? The Cobolt 06-MLD has three different modulation types: on/off, digital and analog. These three modulation types aim to cover most applications the user may have, and they each have very different specifications. •... - Page 37 OWNERS MANUAL | Cobolt 08-01 Series | D0141-K SEPTEMBER 2020 NOTICE The on/off modulation feature should never be used as remote interlock connector. A remote interlock socket is provided for this purpose on the laser head. Digital modulation Digital modulation is the fastest modulation type; it has the largest bandwidth and shortest rise time. Digital modulation requires a 0-5V TTL input signal applied to the digital modulation input female SMA connector on the laser head, and the duty cycle is set by the input signal.

OWNERS MANUAL | Cobolt 08-01 Series | D0141-K SEPTEMBER 2020 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 40 OWNERS MANUAL | Cobolt 08-01 Series | D0141-K SEPTEMBER 2020 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 41 OWNERS MANUAL | Cobolt 08-01 Series | D0141-K SEPTEMBER 2020 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.
