The lab aims to take power lasers from development through to application.
AboutAbout the lab
Realizing the “smart power laser” to solve global challenges.
The Laser Science Lab focuses on research and development of power lasers that deliver the world's highest average power.
It also studies the development of new laser materials, new methods of laser oscillation and amplification, and beam control technologies.
The lab calls a multipurpose system that can be designed on demand through modularization a “smart power laser,” and aims at a wide range of applications such as laser processing, fluorescence analysis, and laser fusion.
On the lab's website, it is introduced as the “PLS group (Power Laser System Engineering Group),” and students are assigned to it as a cooperating laboratory of the School of Engineering and the Graduate School of Engineering.
Key terms
- Power laser
- A high-output laser that can deliver large energy or power.
- Repetition rate
- The number of laser pulses (packets of light emitted for a very short time) that can be emitted per second.
- Petawatt
- One petawatt is 1,000 trillion watts. A unit used to express peak power over a very short time.

ResearchResearch themes
This lab works on developing power laser systems with high energy and high output power. Its research introduction lists high-power lasers, ultrahigh-intensity lasers, and the development of new optical elements.
*Illustrative imageHigh-repetition-rate high-power laser
The lab is developing “SENJU,” a next-generation power laser that produces a high pulse energy at the 100-joule level. Using advanced cooling technology and ceramic gain media, it aims for a high repetition rate of 100 pulses per second.
*Illustrative imageUltrahigh-intensity lasers
By shortening the pulse duration to the extreme, the lab produces extremely high peak power with little energy. The LFEX laser at the Institute of Laser Engineering, Osaka University, reaches 2 petawatts in 1 picosecond, and this lab aims to narrow the pulse to 10 femtoseconds and exceed 10 petawatts.
*Illustrative imageNew optical elements with high damage resistance
Building power lasers requires optical elements and materials that can withstand high laser power. The lab develops and evaluates optical elements with high laser damage resistance, magneto-optical elements, and room-temperature-bonded laser ceramics.
