Datasheet: Fast Switched Diode Laser - FSL 500

The FSL 500 consists of a common control unit and interchangeable laser heads. The control unit contains the power supply, an internal pulse rate generator and a driver stage that allows to control the duration of the laser pulse regardless of the selected amplitude. The driver stage can be operated in three basic modes: internal, slope and level triggered. In both, internal and slope triggered mode the pulse width is controlled by the front panel settings. In the internal mode the driver operates at a base frequency of 12 MHz, which is manually dividable by 2 and 4, and provides an adjustable laser-on duration up to 100 ns. In the slope triggered mode the laser pulse is fired by the falling edge of an external electrical input signal. In the level trigger mode the optical output follows an arbitrary signal pattern of a trigger input, provided that there is an off-time larger than 20 ns between two pulses.
