Page 5: Introduction
OWNERS MANUAL | Cobolt 06-01 Series | D0951-A Introduction The Cobolt 06-01 Series offers a compact form factor and a wide wavelength range in a plug and play format, consisting of high-performance fixed wavelength laser modules; modulated laser diodes (MLD) and diode pumped lasers (DPL) cover a spectral range between 375 nm and 1064 nm, with complete green coverage including 532 nm, 553 nm, 561 nm and 594 nm. -
Page 6: Safety
General All Cobolt 06-01 Series lasers are Class IIIB (CDRH), Class 3B (IEC) laser products emitting less than 500 mW of laser radiation within the ultraviolet (UV), visible (VIS) and near Infrared (NIR) spectrum. The residual at wavelengths not specified on the warning label does not exceed Laser Class 1. -
Page 7: Accessible Emission
OWNERS MANUAL | Cobolt 06-01 Series | D0951-A 2.3. 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 laser product. CAUTION Always wear the appropriate eye protection for all the specified emitted wavelengths. Verify the accessible emission wavelengths and power levels on the warning label before operating. -
Page 8: Safety Features
The laser is equipped with all required safety features as described in the laser safety standard IEC 60825-1. If any part of the delivered equipment is replaced with a part not supplied by Cobolt or if the equipment is not properly grounded system may not conform to CE / CDRH compliance standards listed in section 12. -
Page 9: Equipment Safety
Fiber Pigtailed Option All safety recommendations in section 2 are also valid for the Cobolt 06-01 series fiber pigtailed laser heads. Additionally, heat generated from absorption of laser radiation by particles on the fiber end may increase the probability of ignition hazards in certain environments. -

Page 14: Controlling Emission
Controlling Emission All Cobolt 06-01 lasers are available with emission controls for continuous wave (CW) or modulation mode operation. In this section the different ways to control the emission of each laser will be introduced. It is not recommended to use the continuous wave emission or power level controls to turn the laser ON and OFF with high speed. - Page 15 OWNERS MANUAL | Cobolt 06-01 Series | D0951-A Laser ON and Laser OFF Button The Laser ON and Laser OFF buttons can be used to stop and start emission regardless of the laser run mode (constant power, constant current, power modulation or current modulation mode).

Page 43: Laser Run Modes And Settings
Warming up Cobolt 06-01 lasers are factory set to have no warmup, that is the ‘Warm Up Current’ is set to 0 mA and the ‘Warm Up Time’ is set to 0 seconds. Where applicable, the laser provides a fixed current for a fixed number of seconds. - Page 44 Constant power mode is designed to allow operation of the laser at a fixed output power. The user may input any power setting up to the nominal power. The specified performance of Cobolt 06-01 Series is only guaranteed at 100 % of nominal power.
- Page 45 Digital power modulation: Command modulation Power Modulation run mode in the Cobolt 06-Series can also be utilized to modulate the lasers by software commands in optional combination with external input signals. This part of the run mode is only accessible through software integration and not through the Cobolt Monitor user interface.
- Page 46 The voltage input will determine the ON level of the digital pulses. The power level of Cobolt 06-DPL lasers the exact threshold voltage may vary from laser to laser but is specified to be less than 10 % of the selected voltage range due to the power feedback loop. The modulation speed is not limited and can be used up to 1 kHz.

Page 47: Fault Descriptions
OWNERS MANUAL | Cobolt 06-01 Series | D0951-A Current modulation Current modulation is intended for maximum modulation bandwidth, where modulation speed is more important than power accuracy. Digital current modulation Digital current modulation mode gives the user access to the full bandwidth, in this mode there is no optical feedback loop so the pulse shape of the 06-DPLs may vary. -
Page 48: Troubleshooting
Ensure the laser has adequate heat sinking. 2. Check the base plate temperature (this is displayed in the Cobolt Monitor™ software). If it is outside of the range 20-50 °C the laser may take longer to stabilize the temperature or be unable to do so. - Page 49 OWNERS MANUAL | Cobolt 06-01 Series | D0951-A Low power Check that the laser is in constant power mode (using the GUI or the ‘Laser:RUNMode ConstantPower’ command). 2. Check the power reading using the GUI or the ‘LASer:POWer:reading?’ command. Remove any connector from the modulation inputs socket on the key control box then restart the laser.

Page 50: Warranty And Maintenance
Warranty and Maintenance The Cobolt lasers should not be opened for any reason. The warranty will be void if any of the system units are opened. All laser parameters are set at the factory, and there are no adjustments required (other than those described in this manual for operating in different modulation modes and at different power levels). -
Page 51: Compliance (Cdrh Models Only)
All equipment must be mounted on a common ground plane, such as an optical table. If any part of the delivered equipment is replaced with a part not supplied by Cobolt or if the equipment is not properly grounded, the system may not conform to CE / CDRH compliance standards listed here. - Page 52 Our Locations Cobolt AB (Sales in Norway, Sweden, Finland and Denmark) Solna, Sweden Phone: +46 8 545 912 30 Fax: +46 8 545 912 31 E-mail: info@coboltlasers.com HÜBNER Photonics GmbH (Sales in Germany, Switzerland and Austria) Kassel, Germany Phone: +49 561 994 060-0...
