Latest Patents

Among his latest innovations, Kanehara has developed a sophisticated laser ignition device. This device features a laser oscillation optical system that generates pulsed laser light, which is concentrated into a combustion chamber via a condensing optical element. The housing of the device carefully contains the condensing optical element, while an optical window positioned distally allows the pulsed laser light to pass through. Notably, the design shapes the pulsed laser light into a ring around the optical axis at the point where it exits the optical window.

Another notable patent is the improved laser ignition device, which enhances ignition reliability and minimizes the degradation of the semiconductor laser elements. This invention effectively suppresses the leakage of oscillated light towards the semiconductor laser side through a simple configuration. The device consists of an excitation light source that emits coherent light, an optical element that transmits this light, and a laser resonator capable of oscillating high-energy density light. Additionally, it employs a light-transmissive-reflective film strategically placed between the excitation light source and the laser resonator. This film allows short-wavelength excitation light to pass while reflecting longer-wavelength oscillated light leakage.
