...This is achieved by monitoring a TTL signal via the computer LTP1 port, whose signal is transmitted via RS232 to the laser unit, also used to control basic laser parameters, like pulse divider (laser frequency) and Q-Switch. The Shutter modulation feature allows the user to use the TTL signal to open the laser shutter on demand, controlling the length of the laser pulsed as desired. This method yields reproducible full power laser pulses. The original motivation was to interface mass spectrometer data systems to diverse laser systems. Developed by: Jair Menegon, Paulo Moreira and Thiago Correra - University of São Paulo - Brazil.

The goal of this project is to develop an easily modifiable combination of VHDL firmware and LabView drivers for use with laboratory automation control and data acquisition using Terasic's DE2 board and the ISP1362 USB interface chip.
