Advancements in High-Energy Yellow Raman Laser Technology

This study encompasses new research findings on the resonator configuration of a high-energy yellow Raman laser, and it was conducted jointly by Chairman Hong and Senior Researcher Dr. Alexander Tarasov of LaserOptek.

The Raman laser, which applies Raman scattering discovered by Indian physicist Raman, the first Asian Nobel laureate, to lasers, is known for its high-energy yellow Raman laser technology. This technology can be applied in fields requiring high-performance laser solutions, such as medicine and photography.

The Raman laser can effectively treat vascular lesions such as telangiectasia (strawberry nose), facial flushing, spider veins, vascular malformations, and erythematous papules. While solid-state lasers have been developed to address the limitations of liquid lasers previously used, they have been criticized for their small treatment spot size and low output.

In this regard, LaserOptek's recent research confirming the optimized laser cavity configuration of the Raman laser has paved the way for further development.

According to the study, a flat resonator configuration based on potassium gadolinium tungstate (KGW) crystals showed the most superior performance in terms of energy efficiency among configurations for high-energy yellow Raman lasers. On the other hand, spherical resonators exhibited relatively lower performance in both energy and angle characteristics. Although previous research on Raman lasers existed, none achieved a high output of 11J, as demonstrated in LaserOptek's research.

Therefore, this study's findings are essential for developing Raman lasers with maximum energy conversion efficiency. LaserOptek plans to incorporate these findings into the design of the world's first high-output Raman laser for vascular treatment, which is scheduled for release in the future.

Chairman Hong of LaserOptek stated, "With this research, the optimized laser cavity configuration of the Raman laser has become possible, opening up new horizons in medicine and photography." He added, "We expect significant contributions to the efficiency and stability of the world's first vascular treatment Raman laser, scheduled for release next year."

In addition to Raman lasers, LaserOptek has also launched solid-state UV lasers for the treatment of chronic skin conditions such as psoriasis and vitiligo, as well as high-output picosecond lasers with an effective wavelength of 785nm for whitening and pigment treatment. They are also preparing to launch a picosecond laser specifically for skin tightening in the second half of the year.
