This is a simulation package developed for numerical simulation of ultrashort pulse propagation in optical media and pulse generation from mode-locked lasers. Although the code is primarily intended for investigations of fiber links, fiber amplifiers and fiber lasers, it can be applied to any other setting for which the governing equiations are valid. The physics included in the code is based on a generalized nonlinear Schrödinger equation, including higher order dispersion, stimulated Raman effect, gain with bandwidth limitation and saturation, loss, and saturable absorption. ...

The program does nmr product operator calculations for one, two, three and four spins. Receiver phase cycling is possible in conjunction with pulse phase cycling to simulate coherence pathway selection. An extensive manual and help files are included. Currently running under Linux and Windows.

A programmable signal generator and RF synthesizer for scientific experiments, especially quantum computing and quantum information processing. It includes hardware, firmware, software, and documentation, all under an open source license.

...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. ...
