Interface and operation

Find the corresponding virtual serial port in Communication Port. If not found, click the Refresh button. Click the Connect button. After normal connection, the console will light up and read the current setting value of the controller. Enter the required operating temperature in LD Temp Setpoint and click Set Temperature to set it. The Bias slider sets the constant operating current value, and the Limit slider sets the maximum limiting current. Driver (VCSEL) and Driver2 (SOA) control the current of the two channels respectively. After setting the parameters, click Set Parameters below to send the parameters to the instrument. Click Save All Settings to save all parameters in the instrument.

Click Run:DC to start the laser with the set current value. The Limit slider is used to protect the laser. It can also limit the current under external input conditions. Please set it to the maximum operating current in the laser parameter table.
