The T165 Laser Pulser incorporates an edge triggered pulse generator with 150 picoseconds nominal rise and fall times into a butterfly or TO-packaged laser. 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 T165 offers easily adjustable current, bias, and pulse width settings. It is compatible with several Highland Technology digital delay and pulse generators, including:

For a laser driver without a built-in pulse generator, see the T160 Laser Driver.
