Abstract
Optical apparatus includes a laser, which is configured to output a first optical pulse train at a controllable pulse repetition rate (PRR). An optical coupler is configured to combine the first optical pulse train with a second optical pulse train received from a reference source at a reference PRR. An optical detector is coupled to output an electrical beat signal in response to constructive interference between the combined first and second optical pulse trains. Control circuitry is configured to adjust the PRR of the laser responsively to the electrical beat signal.

Optical apparatus, comprising:
- a laser, which is configured to output a first optical pulse train at a controllable pulse repetition rate (PRR);
- an optical coupler, which is configured to combine the first optical pulse train with a second optical pulse train received from a reference source at a reference PRR;
- an optical detector coupled to output an electrical beat signal in response to constructive interference between the combined first and second optical pulse trains;
- and
- control circuitry configured to adjust the PRR of the laser responsively to the electrical beat signal.
A method for controlling a laser, which outputs a first optical pulse train at a controllable pulse repetition rate (PRR), the method comprising:
- optically mixing the first optical pulse train with a second optical pulse train received from a reference source at a reference PRR, thereby generating an optical beat signal in response to constructive interference between the first and second optical pulse trains;
- and
- adjusting the PRR of the laser responsively to the optical beat signal.
