The T160 Laser Driver features laser drive pulse widths down to 300 picoseconds FWHM and ensures sharp turnoff and minimal optical tails. The signal path is essentially DC coupled, but duty cycle is limited to 60% and laser ON time is limited to 50 microseconds. It is suited to applications in pumped-fiber lasers, fluorescent decay analysis, LIDAR, and laser-based materials processing. The 2" by 2" design connects directly to standard 0.1" pin-pitch butterfly laser packages, making it ideal for OEM use in laser systems.

The T160 offers easily adjustable current and bias settings. It is compatible with several Highland Technology digital delay and pulse generators including:

For a laser driver with a built-in pulse generator, see the T165 Laser Pulser.
