    Abstract: PROBLEM TO BE SOLVED: To provide a waveform reconstruction device capable of easily reconstructing the accurate time waveform of an optical signal without using an ultrafast time gate or a reference light source. SOLUTION: The waveform reconstruction device 140 includes: a phase spectrum calculation section 143 which calculates power spectrum of an output optical signal with respect to each of input optical signals with multiple intensities when a phase spectrum of each of the input optical signals with multiple intensities is assumed to have a predetermined phase spectrum, by simulating propagation of the input optical signal through an optical fiber using a parameter relating to self-phase modulation of the optical fiber, and calculates, as the phase spectrum of the input optical signal, the predetermined phase spectrum in which the difference value between the calculated power spectrum and a measured power spectrum is equal to or less than a predetermined threshold value; and a waveform reconstruction section 144 which reconstructs the time waveform of the input optical signal by frequency/time transforming the calculated phase spectrum and the power spectrum of the input optical signal.

    Abstract: A terahertz spectrometer is provided to achieve the miniaturization of the terahertz spectrometer by inducing a pulse light to an emitter through an optical fiber without using an optical lens. A terahertz spectrometer includes an optical fiber(11C) and an emitter(12), and the emitter is distributed from a gain fiber configuring an ultra-short pulse oscillator. The emitter generates a terahertz wave by using the pulse light that passes through the optical fiber via the gain fiber, and the optical fiber offsets the spreading of the pulse width of the pulse light outputted from the gain fiber.

    Abstract: A system and method of optical spectrum analysis that circumvents the trade-off between resolution and sensitivity by combining two spectral measurements: a first spectrum (102) from first spectral measurement means (240), having high resolution and low sensitivity; and a second spectrum (103) from second spectral measurement means (220), having lower resolution but higher resolution. The input of the of the first spectral measurement means (240) is amplified by an optical amplifier (230), being the effects induced by said amplifier (230) on the first spectrum (102) corrected at processing means (270) by comparison with the second spectrum (103).

    Abstract: A system (1; 2; 3) for coherent Raman spectroscopy, comprises a first optical parametric amplifier (30) providing a first light pulse (100), a pulsed laser (20) providing a second light pulse (200) such that a first fraction (201) of the second light pulse (200) pumps the first optical parametric amplifier (30), and a cw-laser (10) seeding the first optical parametric amplifier (30).
