A true representation of beam quality occurs in the Far-field and directly relates to a focused beam application.

  • Page 34: External Power Control

    VersaLase™. The Stradus VersaLase™ provides the capability to control the laser power at a maximum bandwidth of 500 kHz. Some configurations of the Stradus VersaLase™ contain non-diode type lasers which may have a different bandwidth for External Power Control. A dedicated Modulation Ground is available for each channel and is required to meet specified performance.

  • Page 35: Digital Modulation (Optional)

    By inputting standard TTL voltage levels into the SMB connector, the laser output can be modulated from DC to 200MHz (for diode lasers only). Some configurations of the Stradus VersaLase™ contain non-diode type lasers which may have a reduced bandwidth for Digital Modulation. Computer control is required to set the laser in “Pulse Mode”.

    10.6.3 Digital Modulation Certain types of lasers in the Vortran Stradus VersaLase™ system are able to operate in Digital Modulation mode. This mode is selectable with the “Digital Modulation” Button. When “On” is selected the laser output is modulated as a function of the TTL voltage level input at the SMB connector.

    10.6.4 External Control The External Control function provides the ability to control the laser power directly with an analog voltage. When “OFF” is selected, the laser operates in a constant power mode, based on the present power setting. When “ON” is selected, the laser power is directly controlled by the voltage applied to the external control input.

    10.6.5 Emission The Emission indicator provides the capability to start and stop laser emission. When “ON” is selected, laser emission will be established following the 5 second CDRH delay. If the interlock is open or a fault condition exists, laser emission is not possible. Under these conditions, if “ON”...

    10.6.7 Base Plate Temperature The base plate temperature gauge displays the present measured base plate temperature. The base plate temperature is measured by the microprocessor and is updated continuously. Once again, green represents the normal and safe operating range. Yellow indicates a level of temperature that will allow the laser to operate, but is not recommended for long-term operation.

    10.6.8 Diode Temperature or Module Temperature The present diode temperature or module temperature is displayed as a numerical value with no associated scale. This diode temperature is set at the factory to ensure long-term reliability and maintain the specified optical propagation parameters. The module temperature is the temperature of the laser device for other than diode lasers.

    10.7 Terminal Screen The terminal screen allows the user to communicate directly with the Vortran Stradus VersaLase™ System. This screen provides flexibility to set controller parameters or query specific controller parameters using the list of commands and queries. As a secondary function, the user can test custom laser applications, by using a script containing a series of parameters.

    50KHz. Due to the nature of some types of non-diode laser technologies, certain lasers in the Stradus VersaLase™ will not be able to achieve a 50kHz modulation rate using the Laser Enable Modulation method. The Digital Modulation or External Power Control Methods may instead be used.

  • Page 79: Digital Modulation (Optional)

    11.3 Digital Modulation The output of the Stradus VersaLase™ Laser System can operate in a Continuous Wave or Digital Modulation mode. Prior to setting the laser into Digital Modulation mode, the voltage levels of the input to the SMB connector should be verified using an oscilloscope terminated at 50 ohms.

    12.0 Troubleshooting Guide 12.1 Resolving Faults If a fault occurs, the Vortran Stradus VersaLase™ will set the Fault Pin on the I/O connector to a TTL high level. The fault pin is accessed with the I/O connector DE-25 Pin 3. The associated ground reference is found on the I/O connector DE-25 Pin 11.

    Rapid changes in temperature may cause laser emission to be interrupted until the diode temperature stabilizes. The Vortran Stradus VersaLase™ provides temperature protection for the contained lasers. If a temperature fault occurs, laser emission will be interrupted until the temperature returns to a safe range.
