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.
The AVO-9C, -9E, -9R, -9F1, and -9F2 families are designed for operation at much higher frequencies. The AVO-9C family offers 100 mA amplitude, 0.5 to 10 ns pulse widths, 300 ps rise times, and frequencies of 10 kHz to 25 MHz. The AVO-9E family offers amplitudes to 400 or 800 mA, 10 to 200 ns pulse widths, 300 ps rise times, and a PRF up to 10 MHz.
The -C versions provide outputs similar to those of the -B models, but do not include the GPIB or RS-232 interfaces or LCD display. The output parameters are controlled by front-panel range switches and one-turn vernier controls.
