    • An optical cell and systems such as lasers, optical amplifiers, interferometers, spectrometers, delay lines comprising said optical cell are described. The optical cell comprises at least one telescope and is configured such that light provided to the optical cell makes at least one transit through the telescope in both a first or forward direction and a second or reverse direction opposite to the first or forward direction before exiting from the cell. In embodiments, the telescope is a folded telescope (10), the folded telescope comprising a first retro-reflector (15), and at least one positive optically powered surface (20); and the optical cell further comprises at least one counter reflector (30), wherein the first retro-reflector and the at least one counter reflector are configured to define a cavity or chamber therebetween; at least one input (40) for allowing light to be input to the cavity; and at least one output (45) for allowing light to exit from the cavity.

    • A method for use in controlling a passively Q-switched laser apparatus (110) comprises triggering pumping of a passively Q-switched laser apparatus at a pump trigger time, measuring an emission delay between the pump trigger time and a time of emission of a Q-switched optical pulse from the laser apparatus. The method further comprises using the measured emission delay and a target time for the emission of a further Q-switched optical pulse from the laser apparatus to determine a further pump trigger time. The method may be used for improving the timing of emission of Q-switched optical pulses and may, in particular, serve to suppress pulse-to-pulse timing jitter in particular, though not exclusively, for laser target designation. The laser comprises an end mirror (122), an active gain medium (126), a passive Q-switch (128), an output coupler (124), a beam splitter (146), a photodetector 144), the electrical signal (148) of which is evaluated by a controller (140). The controller provides information to the laser diode driver (132) which drives the laser diode (130) emitting light (136) for pumping the active gain (126). Jitter in the repetition rate of the passively Q-switched laser can be reduced by pump power control.
