SS-OCT Laser Engine

Delivery is Here!

Congratulations, your Axsun SS-OCT Laser Engine has been delivered! First inspect the packaging for external signs of damage. If there is any obvious physical damage, take photographs and request that the carrier's agent be present when the packaging is opened.

NOTE: Retain the shipping container and packing materials so that they may be reused if necessary.

Remove your Engine from its packaging and confirm that all components are present and not damaged. If a component is missing, notify Axsun. If a component appears damaged, notify Axsun and the carrier then follow the carrier's instructions for damage claims.

What's in the Box?

NOTE: This guide includes information for several physical configurations in which Axsun lasers are manufactured and packaged. Please select the tabbed content relative to your specific configuration: Benchtop (with enclosure), Standard OEM (with or without EMI shield), or Small Form Factor OEM (SFF). A summary of all physical configurations can be found here.

Installing OCT Host Software

Follow these instructions to install the USB device driver and the OCT Host application (OCTHost.exe) on your Windows PC.

NOTE: Software media and manuals may not be physically included with your laser. Please visit www.axsun.com/downloads for up-to-date downloads. Manuals and other documentation are available in this Knowledge Base linked from the Table of Contents in the left sidebar.

Making Connections

WARNING: Insure the stated environmental requirements are satisfied before connecting and operating your Engine. Operation of the Engine outside of the stated environmental requirements could cause performance degradation or damage.

NOTE: Before optical fiber connections are made, perform fiber endface inspection (and clean if necessary) per industry standards.

WARNING: Stop laser emission prior to making or breaking fiber optic connections. This is especially important for lasers in the 1060 nm spectral range which use smaller fiber core diameters that are succeptible to endface damage when exposed to high power densities.

Benchtop Enclosure
Standard OEM
Small Form Factor OEM
  • Connect one end of the fiber optic patch cable supplied with your Engine to the enclosure's FC/APC bulkhead adapter and connect the other end to your desired external component (e.g. OCT interferometer fibers).

  • Connect the AC/DC power adapter via AC power cable to mains power (100-240 VAC).

  • Plug the DC connector on the power adapter into its receptacle on the back of the Engine enclosure.

  • (Optional) Connect the USB cable between the type-B USB port on the back of the Engine enclosure and an available USB 2.0 port on a Windows PC.

  • (Optional) Connect the Sweep Trigger and K-Clock outputs to an appropriate oscilloscope or digitizer using an SMA-terminated coax cable (50 Ohm).

  • Insert the key supplied with your Engine into the power switch keyhole and turn the key switch to the ON position.

The startup sequence takes approximately 10 seconds. During this time, the power indicator on the front enclosure may blink while the Engine performs its start-up protocols and self-test.

WARNING: Always connect the fiber patch cable between the enclosure's FC/APC bulkhead adapter and your external component before powering-on the Engine and starting laser emission. Damage to the core of the unconnected fiber behind the bulkhead adapter can occur when exposed to high power densities.

  • Connect the Source output optical fiber to the desired external component (e.g. OCT interferometer fibers).

  • Connect the AC/DC power adapter via AC power cable to mains power (100-240 VAC).

  • Connect one 2x3 output of the power "Y" cable to the Engine board's power receptacle.

    • (The additional 2x3 output is for an optional DAQ and can be left unconnected.)

  • (Optional) Connect the Interface Board to access the Sweep Trigger and K-Clock outputs.

  • (Optional) Connect the USB cable between the mini-B USB port on the Engine and an available USB 2.0 port on a Windows PC.

  • Plug the DC connector on the power adapter into its receptacle on the power "Y" cable input to apply power to the Engine.

  • Connect the Source output optical fiber to the desired external component (e.g. OCT interferometer fibers).

  • Connect the AC/DC power adapter via AC power cable to mains power (100-240 VAC).

  • Connect one 2x3 output of the power "Y" cable to the Engine board's power receptacle.

    • (The additional 2x3 output can be left unconnected.)

  • (Optional) Connect the Sweep Trigger output to an appropriate oscilloscope or digitizer using an SMA-terminated coax cable (50 Ohm).

  • (Optional) Connect the USB cable between the mini-B USB port on the Engine and an available USB 2.0 port on a Windows PC.

  • Plug the DC connector on the power adapter into its receptacle on the power "Y" cable input to apply power to the Engine.

Laser Emission

The default power-on laser emission behavior is configurable as Laser-ON or Laser-OFF. Your laser will initially behave depending on the setting configured at the factory. (Contact Axsun to reconfigure your laser for a different power-on default behavior.)

If your Engine's default power-on emission state is Laser-ON, then swept spectrum optical energy will be emitted from the optical output automatically:

  • after approximately 10 seconds from turning the key switch to the ON position on a Benchtop engine. A laser indicator will be lit on the Benchtop engine while the laser is emitting.

  • after approximately 10 seconds from applying power to a Standard OEM or SFF OEM engine.

If your Engine's default power-on emission state is Laser-OFF, enable laser emission by pressing the Run button in OCT Host on the Engine Control tab.

Disable laser emission without powering-off the Engine by pressing the Stop button in OCT Host on the Engine Control tab.

Verify laser emission is on or off using an optical power meter connected to the Source output fiber, or by viewing the emitted light on an infrared phosphor card.

NOTE: Laser emission can also be enabled and disabled through:

Powering Off

If your Engine is connected to a PC with software control, it is good practice to first disable laser emission prior to powering-off the Engine. To power-off your engine:

  • on a Benchtop engine, turn key switch to the OFF position.

  • on a Standard OEM or SFF OEM engine, unplug the power cable.
