Phase-locked laser driver
Electro-Optical Products

The PLD-2C driver phase locks two choppers. The [sub]system consists of two resonant optical choppers (type CH), chopper "A" and chopper "B", in a MASTER/SLAVE mode, to provide ultra stable modulating beam motions. The system can be used as a "stand alone" unit, in the laboratory or as a portable instrument, or incorporated into a larger instrument/system.

Chopper "B" is phase locked to chopper "A" (the slave is locked to the master). The phase relationship to the master is factory set to customer's requirement (0° to 360°) and is front panel adjustable in a range of +/-45° min. The driver can be a fully integrated driver with front panels controls and internal power supplies or a printed circuit board level driver. The dimensions of the cased driver are: 12" × 10" × 3.8". The PLD-2C-PC driver is a printed circuit board level driver, which requires an external +/-15V DC power supply.
