Scientists create highly potent ultraviolet laser with LBO crystals

The Chinese Academy of Sciences researchers have made a significant breakthrough in the field of lasers by achieving the highest power output for 193 and 221 nm lasers using a LBO crystal. This achievement opens up possibilities for more applications in the deep ultraviolet (DUV) spectrum.

Lasers in the DUV spectrum are already used in various fields such as defect inspection, spectroscopy, lithography, and metrology. However, the ArgonFluoride (ArF) laser has been the go-to option for generating high-power 193 nm lasers for applications like lithography. With this new achievement, LBO crystals may present a viable alternative for achieving even higher power output in the DUV spectrum.

This breakthrough is significant as it could lead to advancements in existing DUV applications and enable new possibilities in the field. The use of LBO crystals could also potentially reduce costs and improve efficiency compared to traditional ArF lasers.

Overall, this achievement by Chinese Academy of Sciences researchers marks a significant milestone in the field of lasers and their application in various industries.

In conclusion, this study shows that LBO crystals can achieve higher power output for 193 and 221 nm lasers than ArF laser. This opens up new possibilities in deep ultraviolet (DUV) spectrum applications such as defect inspection, spectroscopy, lithography, and metrology. This breakthrough is significant for various fields as it presents a viable alternative to traditional ArF laser with potential cost savings and improved efficiency.
