We present simple formulas for the diffraction efficiencies of a binary phase grating that performs array illumination with ultrashort pulse beams. Using scalar diffraction theory, we formulated the efficiencies as a function of pulse spectral width

We report an achromatic cascade optical system for multifocusing ultrashort pulse beams in its application in high-precision materials processing. The challenge is to eliminate the beam-radius-dependent pulse broadening or pulse front distortion from

We investigated spatiotemporal evolution of expanding ablation plume of aluminum created by a 100-fs, 1014–1015-W/cm2 laser pulse. For diagnosing dynamic behavior of ablation plume, we employed the spatiotemporally resolved X-ray absorption spectro

We demonstrate the generation of ultrabroad bandwidth attosecond continua extending to sub-50-as duration in the extreme ultraviolet (EUV) region based on a 1.6-cycle Ti:sapphire laser pulse. The combination of the amplitude gating scheme with a sub-

Current conventional endoscopy often misses flat early gastric cancers (0-IIb) because they are sometimes invisible. We experienced a case of small flat early gastric cancer that had been missed by normal-caliber conventional endoscopy. By small-cali

We report a cascade optical system for multifocusing ultrashort pulse beams, particularly sub-50-fs pulses. System achromaticity is key to simultaneous compensation of the spatio-temporal pulse distortions. In this system, diffractive and refractive
