3 Operation
3.1 General description
The id300 is a short-pulse laser source. The wavelength is set at the factory and
cannot be changed by the user. A Fabry-Perot or a Distributed-feedback laser can be
mounted at the factory. Two wavelengths are available:
 1310nm
 1550nm
The id300 is triggered externally, via a trigger input, to produce sub-nanosecond laser
pulses with a repetition rate ranging from DC to 500MHz. The trigger input is set at the
factory and cannot be changed by the user. Several inputs are available:
 NIM
 ECL
 PECL
 LVPECL
 TTL
 TTL 50Ω
3.2 Using the id300 SPLS
Once connected to the main, the green LED will turn on. Connect the trigger source to
the trigger input using the BNC connector on the front panel. The trigger input of the
instrument connected to the id300 should be compatible with the trigger input of the
id300. The id300 will produce short laser pulses at the repetition rate set by the trigger
input. The repetition rate can be varied from 0Hz (DC operation) to 500MHz. Each
laser pulse has duration of typically 300 ps.
The operating principle is illustrated in Figure 3.1 in the case of a NIM input trigger
signal.
