Introduction

Kazuaki Sajiki is a notable inventor based in Fujisawa, Japan. He has made significant contributions to the field of laser technology, holding a total of 2 patents. His work focuses on innovative methods and devices that enhance the efficiency and effectiveness of laser applications.

Latest Patents

One of Sajiki's latest patents is a gas laser device. This invention features a recess on the upper surface of a cover sealing a laser chamber, which accommodates a plurality of capacitors. These capacitors apply discharge voltage across a pair of discharge electrodes, thereby decreasing the cross-sectional area of a circuit loop that passes discharge current. In a modified embodiment, a preliminary ionization gap is provided for a return rod that constitutes the circuit loop.

Another significant patent is a method of and apparatus for quantitative analysis in accordance with CARS (Coherent Anti-Stokes Raman Scattering). This method involves a first system filled with a material to be measured and a second system filled with a reference material of known concentration, arranged in series. First laser light of a specific frequency for excitation is applied to both systems, along with second laser light of wide bandwidth. The light that passes through these systems is directed to a spectrograph equipped with a multi-channel detector. Quantitative analysis is performed based on the intensity ratio of signal outputs generated in different channels corresponding to the material being measured and the reference material. Notably, anti-Stokes' light emitted between rotational levels of hydrogen is utilized for the quantitative analysis of hydrogen.
