  • Page 23: Laser Description

    Laser Description The OneFive Origami XP and Origami XPS are a series of single chassis, microjoule femtosecond lasers. The lasers provide a stable and low-noise pulsed beam at a wavelength of 1030 nanometers with high pulse contrast. Due to their hardened construction, the lasers can operate in a wide range of ambient conditions.

  • Page 24: Power Supply

    The laser requires an external 24 VDC power source connected to its power input connector. The power can be supplied from your own source or from an NKT Photonics power supply. The NKTP power supply is controlled by a key switch as a safety feature to prevent unauthorized operation.

  • Page 25: Harmonic Generator Modules

    Harmonic generator As an accessory option, a harmonic generator can be mounted on the laser to modules convert the output beam wavelength. Depending on the wavelength conversion required, NKTP can supply the following harmonic generators for use with the laser: Second Harmonic Generator (SHG) –...

  • Page 26: Figure 3 Second Harmonic Generation Module - General View

    SHG (dual port) An SHG module converts the laser’s 1030 nanometer pulse wavelength to a green output pulse at 515 nanometers. Each pulse contains up to 20 microjoules (or up to 40 microjoules for the XPS) of energy with a width of less than 400 femtoseconds. The modules are hermetically sealed and include a desiccant to support operation in industrial environments.

    Chassis Types The OneFive Origami XP Laser series consists of two separate chassis models, each classified by its thermal regulation system. This chapter describes the characteristics of the thermal regulation for each chassis type. Air-cooled OneFive Origami XP The air-cooled chassis of the OneFive Origami XP laser uses a fan plenum shelf with five fans to thermally regulate the laser operation.

  • Page 40: Water-Cooled Onefive Origami Xp

    Water-cooled OneFive Origami XP Water-cooled OneFive Origami XP This chassis uses water-cooled channels to regulate the temperature of the laser operation. The laser is equipped with two male straight hose couplings through which the inlet and outlet cooling water is circulated. The water is cooled using an external cooling system consisting of a chiller combined with a controller that has at the minimum, a temperature set point and flow control capability.

  • Page 43: Mechanical Installation

    Mechanical Installation The lasers generate a substantial amount of heat that must be dissipated. To dissipate the heat, the lasers are available in two different chassis versions defined by their temperature regulation system. This chapter provides information on how to mechanically install the air and water-cooled variants of the laser.

  • Page 44: Installing The Air-Cooled Chassis

    Installing the Air-cooled chassis air flow is adjusted based on the lasers operating temperature. There should be a clearance gap in front of the intake grill and exhaust vents to allow the free flow of air. Water-cooled The laser is cooled by water that is pumped and circulated through the laser from an external chiller.

The coolant can flow in either direction through the Table laser, meaning the coolant supply and return hoses from the chiller can be connected to either of the laser’s straight hose couplers.
  • Page 48 Installing the water-cooled chassis To protect the aluminum cooling circuit, it is recommended to use a coolant containing an anti-corrosive additive. Required water flow and water temperature may vary and is dependent on the actual optical system parameters. Caution: The cooling system is constructed entirely from aluminum. To avoid cor- rosion, make sure not to connect other items to the cooling circuit except when agreed with NKTP.

  • Page 52: 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 53: Connecting An Interlock Switch

    Disabled 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 closed state using a tool.

  • Page 54: Connecting Power

    Connecting power Procedure 2 Connecting the door interlock circuit Action Install a switch that opens when the door accessing the laser enclosure is opened.

  • Page 60: Examples Of Laser Output Pulses Using Dgi

    Digital Gate Input Setting the DGI port logic The port logic can be set to either “Active-Low” or “Active-High”. If “Active-Low” is selected, a low signal level at the port will enable laser emission from the AOM. If “Active-High” is selected, a high signal level at the port will enable laser emission from the AOM.
