The AVO-9 series offers a range of easy-to-use, ultra-highspeed pulsed laser diode drivers. Each model in the AVO-9 series consists of an instrument mainframe and an output module connected to the mainframe by a short (2 ft / 60 cm) coaxial cable. The mainframe generates a voltage pulse that is supplied to the output module. The output module has a special high-speed socket designed specifically for the user's particular laser diode, and a series resistance. This arrangement provides a user-friendly plug-and-play setup, without degrading performance. Different output modules can be ordered if the user needs to drive more than one type of diode.
