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…
