摘要： A sampling light source (10) generates a pulse sequence of sampling light having a pulse width smaller than that of target light (a) and a single plane of polarization. A polarization beam splitting unit (11) splits each of the sampling light output from the sampling light source, and the target light into two light components having planes of polarization shifted 90° from each other, multiplexes each pair of split sampling and target light components having planes of plane of polarization shifted 90° from each other, and outputs the respective multiplexed light components to different optical paths. A pair of nonlinear optical members (1a, 1b) each generate a cross-correlation signal based on the sampling and target light components output from the polarization beam splitting unit to each optical path and having planes of polarization shifted 90° from each other as sum frequency light. A pair of photodetectors (7a, 7b) each convert the sum frequency light output from each of the pair of nonlinear optical members into an electrical signal. A signal processing unit (12) adds the electrical signals output from the pair of photodetectors, processes the resultant electrical signal, and displays its pulse waveform. With this operation, the pulse waveform of the target light can be accurately measured regardless of variations in the polarized state of the target light.

摘要： A nonlinear optical crystal (10) is composed of 2-adamantyl-5-nitorpyridine (AANP) allowing the type 2 phase matching to the sampling light and a measuring object light, emitting a sum frequency light of the measuring object light and the sampling light, with the polarization directions thereof being perpendicular to each other, when the sampling light and measuring object light multiplexed by a multiplexer (3) are entered. When the sum frequency light is emitted through the nonlinear optical crystal (10), a control portion (2, 5) controls the polarization direction of the sampling light so as to be parallel to a predetermined reference axis located within a plane perpendicular to a phase matching direction of the nonlinear optical crystal. The predetermined reference axis is a single axis maintaining parallelism with the crystal axis of the nonlinear optical crystal even if the wavelength of the inputted light is changed.

摘要： A first tunable wavelength pulse light source (22) is driven by a reference signal to emit a first optical pulse. An optical demultiplexer (24) demultiplexes a first optical pulse emitted from the first pulse light source (22) into a reference optical pulse and an incident optical pulse to be sent into an object to be measured. An optical multiplexer (26) multiplexes the reference optical pulse and an outgoing optical pulse passing through the object to output multiplexed light. A second pulse light source (23) generates a second optical pulse which is synchronous with the first optical pulse and delays a predetermined time for each period of the first optical pulse. A sampling unit (27, 27a, 27b) receives the multiplexed light and the second optical pulse to obtain an optical pulse train signal proportional to the intensity of the multiplexed light obtained in synchronism with the second optical pulse. From the optical pulse train signal from the sampling unit (27, 27a, 27b), a signal processor (37) obtains an envelope formed by peaks of individual optical pulses forming the optical pulse train. The wavelength dispersion of the object is obtained by measuring the delay time of the outgoing optical pulse passing through the object on the basis of intervals between the peaks of the envelope.
