Abstract:
Apparatus for providing optical radiation ( 1 ), which apparatus comprises a laser diode ( 2 ), a pulse generator ( 9 ), and a modulator ( 5 ), wherein: the pulse generator ( 9 ) is configured to emit picosecond pulses; the modulator ( 5 ) is configured to emit nanosecond pulses; the laser diode ( 2 ) has a first terminal ( 6 ) and a second terminal ( 7 ); the pulse generator ( 9 ) is connected to the first terminal ( 6 ); and the modulator ( 5 ) is configured to bias the laser diode ( 2 ) below a lasing threshold ( 8 ) of the laser diode ( 2 ), and the apparatus being characterized in that: the modulator ( 5 ) is connected to the second terminal ( 7 ); the pulse generator ( 9 ) comprises a semiconductor junction ( 32 ) connected to a differentiator ( 4 ); the semiconductor junction ( 32 ) is such that electric current flowing through the semiconductor junction ( 32 ) can be turned off more quickly than it can be turned on; and the differentiator ( 4 ) is such that a step change that occurs when the electric current flowing through the semiconductor junction ( 32 ) is turned off is converted to an electrical pulse, thereby gain switching the laser diode ( 2 ) such that it emits an optical pulse ( 10 ) having an optical pulse width ( 11 ) less than 10 ns.

Claim (Index 31):
A method according to  claim 20 , and comprising configuring at least one optical reflector to receive optical pulses emitted by the laser diode, which optical reflector is positioned at a third distance from the laser diode, and wherein the third distance is selected such that optical pulses reflected by the optical reflector overlap temporally with successive ones of the optical pulses.
