2: Set-up and Operation
Note
Note that the switch returns to the center position after you press it. At this point, it can
function as a manual reset.
4. In the event of a power interruption, power failure or interlock break, the laser is automatically
disabled. To re-enable it, toggle the
Laser On switch to back to the ON position.
Operation in External Power Control Mode
The Multimode Spectrum Stabilized Laser provides the capability of adjusting the power remotely via
computer or signal generator in External Power Control mode. Use the following procedure:
►
Procedure
1. Make sure that a BNC cable is connected to the Control port on the rear panel as described in
Set-
up for Operation in External Power Control Mode
.
2. Apply a DC bias between 0 (zero power) and 1 (full power) Volt to modulate the laser or to
adjust the laser’s output power. The unit can be modulated at rates up to approximately 300 KHz.
3. Push the Laser On switch (on the front panel). The laser then outputs a variable amount if output
power dependent on the DC bias voltage that has been applied to the Control port on the rear
panel.
Using the Remote Interlock Feature
The Remote Interlock is a safety feature that automatically shuts down the laser when a trigger such as a
door or an enclosure opening occurs. You may decide to enable a remote interlock mechanism when
integrating the laser into a laboratory or system environment.
The interlock is located on the rear panel and uses an RJ-11 plug. The Remote Interlock is normally an
open circuit, so the provided RJ-11 connector or a user-configured closed loop interconnect MUST be in
place for proper function of the laser module. To enable the Remote Interlock, you must obtain an RJ-11
plug (or modify the plug provided) and create a closed circuit between the two signal terminals of the
plug and insert the closed-circuit RJ-11 plug into the Interlock jack.
The laser functions normally when is senses a closed circuit, but it will disable laser output when it
detects an open circuit. To re-enable the laser function, you must make sure that the interlock is a closed
circuit, and then manually reset the laser by toggling the
Laser On switch on the front panel to the ON
position.
