Abstract:
A self-seeded optical parametric amplifier (OPA) system includes a cavity mirror, a wavelength conversion unit, and a dichroic filter. The cavity mirror is configured to allow high transmission for an input laser beam and high reflection for a feedback beam. The wavelength conversion unit is configured to convert the input laser beam into a signal laser beam and an idler laser beam. The dichroic filter is configured to allow one of the signal laser beam and the idler laser beam to pass through the dichroic filter and reflect the other one onto a feedback path.

A laser system and a laser outputting method are disclosed. The method comprises: providing a oscillator, wherein the oscillator comprises a pump light source, a cavity and a mode locked controller; utilizing the pump light source to emit a pump light into the cavity; outputting first laser pulses to the spectrum converter; utilizing a wavelength conversion chip of the spectrum converter to convert the first laser pulses to second laser pulses; utilizing at least one photo-detector to detect a power of the second laser pulses; controlling the mode locked controller to modulate a mode-locked status of the cavity when the power of the second laser pulses is lower than a threshold value.
Abstract:
The present invention provides a measurement system of real-time spatially-resolved spectrum and time-resolved spectrum and a measurement module thereof. The measurement system includes an excitation light and a measurement module. The excitation light excites a fluorescent sample and the measurement module receives and analyzes fluorescence emitted by the fluorescent sample. The measurement module includes a single-photon linear scanner and a linear CCD spectrometer. The single-photon linear scanner selectively intercepts a light beam component of a multi-wavelength light beam that has a predetermined wavelength to generate a single-wavelength time-resolved signal, wherein the multi-wavelength light beam is generated by splitting the fluorescence. The linear CCD spectrometer receives the multi-wavelength light beam and generates a spatially-resolved full-spectrum fluorescence signal. With the implementation of the present invention, the spatially-resolved full-spectrum fluorescence signal and the single-wavelength time-resolved signal can be observed at the same time. Thus, the facility of a fluorescence spectrometer is improved.
