Enriching Society Through Light and Laser Technology: The 'April Dream' of Laser Platformer Hikari Kohyo

Our company supports April Dream, a project to make April 1st a day for sharing dreams. This press release is the dream of Hikari Kohyo Co., Ltd.

The illustration at the beginning was created in 2019, our 10th anniversary, imaging the world in 2050 brought about by the development of laser technology.

Under the management philosophy of 'Enriching society with light and laser technology,' our company develops products and services that contribute to the development of a sustainable society. We will pursue the possibilities of light and laser technology and respond with solid technical capabilities to improve convenience and solve various social issues.

1. Femtosecond Laser Processing Machines: Leading the manufacturing of high-performance/advanced semiconductors and ultra-fine processing.

2. Laser Cleaners: Achieving non-contact removal of rust and dirt in the repair of aging infrastructure.

3. LiDAR (Light Detection and Ranging): Sensing technology supporting autonomous driving, pedestrian flow analysis, and advanced monitoring.

■ Precision Micro-machining Using Femtosecond Lasers

— 'Processing without heat' opens up next-generation semiconductors and high-functional materials —

A femtosecond laser is an advanced technology that can process target materials with almost no thermal influence by irradiating the laser for an extremely short time of 10⁻¹⁵ seconds.

This property, called 'cold ablation,' enables micron-level high-precision processing even for high-hardness and brittle materials such as glass, sapphire, SiC, and GaN, which were difficult to process with conventional methods.

In recent years, it has been rapidly spreading not only for research purposes but also as a practical processing technology in the semiconductor and electronic components fields.

As a pioneer in this technology, our company handles glass debonding of semiconductor wafers and difficult processing of power semiconductor materials (SiC, GaN, diamond). Furthermore, we provide optimal processing solutions according to applications through wavelength selection of UV, Green, and IR and advanced beam control technology.

We support the evolution of next-generation semiconductors and industrial advancement by responding to a wide range of processing needs such as fine hole processing, internal modification of transparent materials, and surface texturing.

■ Laser Cleaners

— Efficient infrastructure maintenance with innovative 'cleaning without scraping' technology —
https://www.symphotony.com/products/cleaner/

A laser cleaner is a device that removes rust, oxidation scale, and paint films attached to metal surfaces in a non-contact manner by irradiating laser light.

Since the laser selectively removes only the dirt layer, it is less likely to damage the base material and allows for clean processing without the use of abrasives or chemicals. This leads to a reduction in industrial waste and an improvement in the working environment.

Infrastructure such as bridges, roads, and railways built during the period of high economic growth is aging, and the efficiency of repair and maintenance has become an urgent social issue.

Our laser cleaners respond to thick rust and paint films with powerful condensing technology, and we offer a wide lineup from small lightweight models to high-power models. Optimal operation is possible according to the application at the site.

It contributes to durability and functional maintenance while suppressing the progression of corrosion inside the material. It is a next-generation infrastructure maintenance solution that achieves both labor-saving and environmental load reduction.

■ LiDAR:

— 'Capturing space with light' technology evolves social infrastructure and mobility —

https://www.symphotony.com/lidar/

LiDAR (Light Detection and Ranging) is a technology that irradiates laser light onto an object and precisely measures distance and shape based on the reflected light.

By analyzing the round-trip time of the laser, high-density 3D point cloud data can be acquired over a wide area, making it possible to visualize space with high precision.

In addition to conventional fields such as mapping, surveying, civil engineering, and architecture, this technology is being used in a wide range of fields including autonomous driving, robotics, agriculture, forestry, and pedestrian flow analysis.

Our company develops LiDAR products for diverse applications, including backpack types, handheld types, drone-mounted types, vehicle-mounted types, and 360-degree measurement types. We can respond to all scenes from wide-area outdoor surveys to indoor space measurement and moving body measurement. The acquired data is also used for 3D modeling and digital twin construction, contributing to the promotion of smart cities and infrastructure DX.
