Title: **Inventor Tatsuhiko Yamanaka: Pioneering Extreme Ultraviolet Light Technologies**
Introduction
Tatsuhiko Yamanaka, an innovative inventor based in Suita, Japan, has made significant contributions to the field of extreme ultraviolet light technologies. With a total of two patents to his name, his work focuses on enhancing the efficiency and effectiveness of extreme ultraviolet light sources, which have applications in various scientific and industrial fields.
Latest Patents
Yamanaka's latest patents include:
1. **Extreme Ultraviolet Light Source and Extreme Ultraviolet Light Source Target**
This invention aims to provide a target that emits extreme ultraviolet light with high emission efficiency. The solid target is made from heavy metal or heavy-metal compound, featuring a density between 0.5 to 80% that of the crystal density. When this target is irradiated with a laser beam, it generates plasma from the heavy metal, which emits extreme ultraviolet light at a predetermined wavelength specific to the metal used. Notably, using a SnO target with a density of 24% of the crystal density results in higher emission efficiency at around 13.5 nm wavelength compared to Sn crystal targets.
2. **Laser Beam Focusing Apparatus and Method for Focusing a Laser Beam**
This invention consists of a hollow tube with two opposing openings of differing diameters. A pulsed laser beam enters from the larger opening, reflecting off the inner tube walls and becoming focused as it travels towards the smaller opening. The focused laser beam is then outputted from the smaller opening, demonstrating Yamanaka's expertise in laser technology.
