    OWNERS MANUAL | Cobolt 06-01 Series | D0136-K DECEMBER 2018 Introduction The Cobolt 06-01 Series offers a compact form factor and a wide wavelength span in a plug and play format. 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 405 nm and 660 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 Verify the accessible emission wavelengths and power levels on the warning label before operating. Fiber Pigtailed Option All safety recommendations in section 2.1 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 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 Fel!

  • Page 9: Equipment Safety

    06-MLD lasers with a wavelength greater than 600 nm are particularly sensitive, exercise extreme caution. Electrostatic discharge Always install the laser system to a properly grounded power outlet. Cobolt lasers contain a laser diode which is sensitive to electrostatic discharge (ESD). Fiber care It is important to always make sure the fiber end-face is clean before turning the laser on and before connecting the fiber connector in physical contact with another connector.

To start the laser, turn the key on the Control Box clockwise to the ON position. If it is already in the ON position, turn it to OFF and then ON again.

  • Page 12: 06-Dpl

    OWNERS MANUAL | Cobolt 06-01 Series | D0136-K DECEMBER 2018 06-DPL When delivered the lasers are, by default, set to continuous-wave, constant power mode. As soon as power is supplied to the laser head the auto-start procedure will begin. Light will be emitted once the remote interlock connector is connected, the shutter is open and when the key is turned to the ON position (CDRH model).

  • Page 13: Closedown Operation

    Set your signal generator to give a square-wave, 0-5 V. 2. Connect the input from the signal generator to the SMA connector on the back of the laser head. Choose digital modulation mode in the Cobolt Monitor™ software (see section 9 for software installation instructions).

  • Page 14: Overview

    Overview Cobolt 06-01 Series laser systems consist of four main parts: the laser head, key control box, cable between laser head and key control box, and the power Supply (not shown). Always install the laser system to a properly grounded power outlet.

  • Page 15: Configuration

    OWNERS MANUAL | Cobolt 06-01 Series | D0136-K DECEMBER 2018 Configuration CE/CDRH Compliant The CE/CDRH compliant system is supplied with a key control box, which must be connected, along with a remote interlock connector. Once power is supplied, laser emission starts when the key is turned from the OFF position to the ON position.

    8 hours. The default mode for Cobolt 06-DPLs is constant power. In constant current mode the laser runs at a set current level. In constant power mode the power is monitored on an internal photodiode, and this is used to regulate the current to maintain a constant power level.
  • Page 32 3.5 mm stereo audio plug. The plug should be connected as shown in the figure below. Ground In Cobolt Monitor™ there is a tick box “On/Off Modulation”, which indicates when on/off modulation is active. When this is the case, all other options are greyed out (although the previous mode remains checked, as the laser remembers which state it was in previously).
  • Page 33 The figure below contains a typical power vs. current graph for a Cobolt 06-MLD 405nm laser, showing this behavior. When modulating with an arbitrary waveform, it is possible use a DC offset on the signal generator such that the laser is modulated from this threshold point to the desired maximum signal level.

    OWNERS MANUAL | Cobolt 06-01 Series | D0136-K DECEMBER 2018 The MLD can be used with hybrid digital + analog modulation signals. 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.
  • Page 35 Digital + Analog The 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.
  • Page 36 OWNERS MANUAL | Cobolt 06-01 Series | D0136-K DECEMBER 2018 Settings Optimization in modulation mode Cobolt Monitor™ software allow the user to optimize the laser performance while in modulation mode. During manufacturing the 06-DPLs settings are in digital modulation at 1 kHz and a 50% duty cycle. When modulating with a different input signal the user can expect changes in the pulse shape, peak power and average power.
  • Page 37 OWNERS MANUAL | Cobolt 06-01 Series | D0136-K DECEMBER 2018 TEC LD Adjustment The 06-DPLs optical output power is influenced heavily by the match between the pump diode’s emission spectrum and the laser crystal’s gain spectrum. Modulation mode operation is achieved by direct modulation of the drive current to the pump diode.

    4. Verify the supply voltage is within the range stated in section 4.5. 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 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. The equipment might not conform to the EC directives if any part of the supplied equipment is replaced with a part not supplied by Cobolt or if the equipment is not properly grounded.
