  • Page 5: Introduction

    OWNERS MANUAL | C-FLEX | D0579-B DECEMBER 2019 Introduction C-FLEX is a flexible and compact laser combiner that allows for integration of up to six different wavelengths on a single platform, modulation options for all wavelengths, and configuration with either free beam or fiber coupled beam delivery.

  • Page 6: Safety

    Safety General The C-FLEX laser combiner’s laser classification is dependent on the lasers integrated into the laser combiner system. The sum of the maximum emitted power of all lasers integrated into the laser combiner determines the laser classification. Residual emission of any wavelength not specified on the warning label does not exceed Laser Class 1.

  • Page 7: Beam Hazards

    OWNERS MANUAL | C-FLEX | D0579-B DECEMBER 2019 Beam Hazards It is advised to perform a risk assessment for the facility and equipment prior to using the laser. In the case of integration into a larger system, laser safety compliance must be evaluated in the end product. The device must be handled by skilled personnel experienced with lasers, in a laboratory environment and with access to adequate laser safety equipment.

  • Page 8: Accessible Emission And Eye Protection

    WARNING – The magnetic switches use strong magnets which are attached to the underside of the access panel. Be aware of strong magnetic fields. CAUTION – Alignment and maintenance of the lasers inside the C-FLEX should only be performed by trained personnel with appropriate laser safety equipment.

    The constant power setting is used to regulate the output power level. All lasers are delivered in the most appropriate operating mode for optimized stability. To restore original power level settings refer to the test protocol delivered with the C-FLEX. Location of emission controls in Cobolt Monitor™ Software NOTICE Though the output power setting and drive current can be changed the other laser performance parameters are only guaranteed at 100% of nominal output power.
  • Page 48 In constant power mode each laser has a field where the output power can be set. The power set point for each laser controls the emission from the individual laser heads and not through the C-FLEX aperture. The expected power out of the C-FLEX aperture can be found on the test protocol.

  • Page 49: Pause Emission With Commands

    Combining Constant Power operation and Constant Current operation during alignment When aligning the C-FLEX, one way to stop and start the emission is to set the constant current level to zero and set the constant power level to the nominal output power and then use the mode button in the Cobolt Monitor software to toggle between Constant Power operation and Constant Current operation.
  • Page 50 OWNERS MANUAL | C-FLEX | D0579-B DECEMBER 2019 2. To control the emission of individual lasers during testing and alignment it can be usefull to pause the emission. Send the command ‘l0r’ to temporarily stop emission on all lasers not being tested. The LASER ON emission indicator will remain illuminated.

    Two pin-hole technique Alignment of the C-FLEX can be done by using two pin holes or targets to adjust the beam position and the beam angle. The pin hole closest to the light source is used for beam position adjustments and the second pin hole is used for angular adjustments.

  • Page 74: Vertical Alignment

    OWNERS MANUAL | C-FLEX | D0579-B DECEMBER 2019 Vertical alignment In the case of C-FLEX the beam height can be adjusted independently from the horizontal position and beam angle. After loosening the set screw, adjust the beam height by turning the beam height adjustment wheel until the beam is aligned in the middle of the steering mirror.

  • Page 75: Angular Alignment

    OWNERS MANUAL | C-FLEX | D0579-B DECEMBER 2019 Angular alignment Once the beam is aligned horizontally and vertically the same three screws can be used for tip/tilt adjustments, controlling the beam angle. When adjusting the beam angle, do not use all three screws. As described above, the dark blue and green screws are used for angular alignment, turning all three will translate the steering mirror and change the incident location on the mirror.

  • Page 76: Fiber Alignment

    After the beam is aligned to the aperture the fiber must be aligned within the coupler. The fiber coupler provided with the C-FLEX is supplied with a black tube with a pin-hole in one end. Use this tube to align the system by placing the pin-hole tube in the coupler, maximizing the output power through the pinhole using the corresponding set of adjustment screws on the coupler.
