A burst of pulses at the set repetition rate is emitted each time the laser receives a telegram to initiate the burst. To send telegrams to the laser over it’s RS-232 serial or USB interface, you must implement the NKT Photonics Software Development Kit (SDK). The SDK can be downloaded from:... - Page 39 Menu items Note: The telegram to initiate the burst is sent to register 0x34 (Burst pulses). Burst number (Burst pulses) and repetition rate (Frequency) can be set with either the front panel sub-menus or with registers 0x34 and 0x33 respectively. Note: Software burst mode is not supported using CONTROL.
