    2. This guide uses the term, “laser” to refer to all SuperK FIANIUM laser variants. When information related to any specific variant is noted, the model name is specified. The guide may also refer to NKT Photonics as simply NKTP, the two are one and the same.

  • Page 20: Control

    Optical output CONTROL The laser and its accessories can be managed and configured remotely from a PC using the NKTP CONTROL software. The PC can connect to the laser over either RS232, USB, or Ethernet links. To configure accessories using the same PC, the laser is equipped with an external bus interface which can connect up to eight accessories in a daisy chain configuration.

  • Page 21: Spectral Output

    Optical output Spectral output Figure 2 shows the spectral power density of the three SuperK FIANIUM series models. Figure 2 Supercontinuum output of the laser Collimator The laser’s optical output uses a collimator (see Figure 3) where the laser beam is emitted from.

  • Page 22: Beam Diameter

    A small fraction of the beam power is dumped within the collimator. If the thermal contact between the collimator and the mount or receptacle is inadequate, the collimator can become significantly warm. NKT Photonics recommends that you ensure there is thermal contact between the collimator and its mount/receptacle.

  • Page 42: Connecting The Safety Interlock

    Connecting the safety interlock Connecting the safety interlock To comply with safety regulations and help provide a safe operating environment, the safety interlock of the laser must be connected to a switch activated by an access door to the laser’s enclosure. When the connected switch is opened by the door, it opens the interlock circuit which turns off laser emissions.

  • Page 43: Safety Door Switch

    Interlock Reset Caution: Do not short-circuit the Interlock input. Short-circuiting the interlock cir- cumvents safety regulations and NKT Photonics does not take liability for any in- juries or damage caused by doing so. Caution: The switch connected to the interlock must be of an approved type. Fur- ther, the switch must be installed in a manner so that its operation cannot be fixed in the open state using a tool to defeat its operation.

  • Page 44: Connecting Power

    Connecting power Procedure 1 Connecting the door interlock circuit Action Install a switch that opens when the door accessing the laser enclosure is opened. The switch must comply with local regulations. Connect the switch to the prewired interlock plug using insulated wire. The wire gauge should be at a minimum 26 AWG with a maximum length of five meters.

  • Page 45: Connecting The Optical Output

    Connecting the optical output Caution: Ensure you use an approved cord set when supplying AC mains power. The cord set must be suitable for the laser’s power ratings and be approved by your regional electrical safety regulations.

    SuperK SELECT SuperK SELECT A SuperK SELECT accessory can be fitted to extract multiple specific light wavelengths from the broadband spectrum output of the SuperK FIANIUM laser. The SELECT accessory uses Acousto-optic Tunable Filter (AOTF) technology which uses a tellurium dioxide crystal that diffracts the desired beam wavelength. The specific wavelength diffracted by the crystal is tuned by applying an RF signal to it.
