Sub-shot-noise mid-infrared photothermal measurements using twin beams
Kazuki Hashimoto, Takuro Ideguchi
Mid-infrared photothermal (MIP) measurement probes refractive-index changes induced by mid-infrared (MIR) absorption using visible or near-infrared light and has recently emerged a…
Ghost infrared spectroscopy with bright twin beams
Akira Kawai, Makoto Shoshin, Kazuki Hashimoto +1
Frequency-correlated light offers a route to mid-infrared (MIR) spectroscopy without direct spectral detection in the MIR. Previous MIR ghost spectroscopy has mainly relied on low-…
Pulse-to-pulse spectral phase characterization of mid-infrared pulses at megahertz rates
Zhihao Deng, Zicong Xu, Kazuki Hashimoto +3
Pulse-resolved spectral phase measurement of mid-infrared (MIR) pulses is essential for many applications, from precise waveform control to ultrafast quantum optics. However, conve…
Fiber-based mid-infrared frequency-swept laser at 50 MScans/s via frequency down-conversion of time-stretched pulses
Makoto Shoshin, Takahiro Kageyama, Takuma Nakamura +2
Increasing the sweep rate of mid-infrared (MIR) frequency-swept sources offers significant potential for various high-speed spectroscopy-based applications. While continuous-wave f…
Mid-infrared optical coherence tomography with MHz axial line rate for real-time non-destructive testing
Satoko Yagi, Takuma Nakamura, Kazuki Hashimoto +2
Non-destructive testing (NDT) is crucial for ensuring product quality and safety across various industries. Conventional methods such as ultrasonic, terahertz, and X-ray imaging ha…
Broadband coherent Raman scattering spectroscopy at 50,000,000 spectra/s
Takuma Nakamura, Kazuki Hashimoto, Takuro Ideguchi
Raman scattering spectroscopy is widely used as an analytical technique in various fields, but its measurement process tends to be slow due to the low scattering cross-section. In…
