摘要： A coupling for mounting and positioning photographic, motion picture and video accessories and the like. A mounting sleeve is adapted to be secured to an equipment supporting member. A fixed positioning disc depends from and is integral with the mounting sleeve. A cylindrical shaft is axially coupled to and extends from the fixed positioning disc. A first rotatable positioning disc is disposed about the cylindrical shaft, a frictional stabilizing member being disposed between the fixed positioning disc and the first rotatable positioning disc. A second rotatable positioning disc is annularly disposed about the cylindrical shaft in proximity to the first rotatable positioning disc. The adjacent surfaces of the first and second rotatable positioning discs have disposed therein reciprocally aligned pairs of linear channels of varying width and depth, each pair of linear channels being adapted to receive and secure equipment supporting shafts of differing cross section. A securing handle is coupled to the cylindrical shaft and is adapted to impose an axial force to engage the rotatable discs and thereby securely position each pair of aligned, linear channels at any position along a 360.degree. arc relative to the axis of the mounting sleeve.

摘要： The pulse repetition frequency of an optical pulse generator built with a fiber laser (LAS) is synchronized to a fixed clock frequency (fc). The synchronization is accomplished via means (M) for changing the optical path length of the resonator (RES), which is controlled by a signal from a control device (RE). The criterion for the synchronization is the effective value of an interference signal superimposed on the signal light, which increases with increasing deviation of the pulse repetition frequency from the clock frequency. A portion of the output signal (A) of fiber laser (LAS) is optically/electrically converted by the control device (RE), and the effective value of the interference signal is determined by filtering and rectifying the electrical signal obtained in this manner. After subsequent amplification and regulation, the control signal for the means (M) to change the optical wavelength is obtained. The control signal is additionally modulated with a wobble signal, so that the pulse repetition frequency always varies around the optimum value and is synchronized in this way.

摘要： A passively mode-locked fiber ring laser (LAS) is disclosed for generating optical pulses whose repetition frequency is settable. The mode-locked fiber ring laser (LAS) contains an erbium-doped fiber (ER), a ring resonator (RES), a pump-light source (PUMP), an optical modulator (MOD), and a feedback loop (RS). A portion of the signal light, which is produced by stimulated emission and is composed of a plurality of pulse repetition frequencies, is processed in the feedback loop (RS) into a drive signal which is coupled to the control input of the optical modulator (MOD). The feedback loop (RS) includes an adjustable filter which filters the desired pulse repetition frequency from the signal light. Thus, optical pulses of a given repetition frequency are developed in the ring resonator (RES) and at the output (OUT) of the passively mode-locked fiber ring laser (LAS).

摘要： An optically pumped bistable laser (LAS) with an active laser condition and an excited inactive condition is presented. The bistable laser (LAS) comprises an erbium-doped fiber (ER), a resonator (RES), a pumping light source (PUMP), and optical isolator (ISO), a wavelength-dependent coupler (WDM) and an asymmetrical fiber coupler (FC). Excitation from the excited condition is created by pumping light from the pumping light source (PUMP) into the erbium-doped fiber (ER), to place the bistable laser into the excited inactive condition. Optical pulses, which are coupled in through input (IN), activate the bistable laser (LAS) and enable it to operate both as a pulse generator and a trigger circuit, as a function of pulse duration and/or pulse frequency.

摘要： Known optical amplifiers, which are used in a light transmission path to amplify the light signals to be transmitted, have the disadvantage that the semiconductor lasers, used as pump lasers therein, are very sensitive to feedback.According to the invention, the operating current of such pump lasers (4) is modulated at a high frequency, which causes the pump laser to operate in a multi-mode, thereby making it insensitive to feedback. For example, the operating current is DC, on which AC is superimposed.In the event the optical amplifier has two pump lasers, their operating current is also modulated. Both pump lasers are then advantageously alternately switched on and off at a sufficiently high switching frequency, which also prevents reciprocal interference.
