[Edaily Reporter Kwon Oh-seok] Laser Optic, a company specializing in lasers for skin aesthetics and disease treatment, announced on the 15th that it has officially unveiled its high-power 589nm solid-state vascular laser device, the ‘VASCURA 589’.

Laser Optic held the ‘VASCURA 589 PREMIERE’ event at Dragon City in Seoul on the 13th to introduce the core technology and clinical applications of VASCURA 589. The event began with congratulatory videos from dermatologists around the world and a congratulatory speech by Oh Sang-rok, President of the Korea Institute of Science and Technology (KIST). This was followed by a presentation by CEO Lee Chang-jin on the development background and key features of the device, a review of the history of vascular laser technology by Dr. Ko Woo-seok of JMO Dermatology, and a presentation on clinical efficacy and expanded indications by Dr. Oh Chang-geun of OZ Dermatology.
Based on LaserOptic’s proprietary KGW Raman laser technology, the Vascula 589 is characterized by its ability to generate high-power output at a 589nm wavelength—a feat previously difficult to achieve with solid-state lasers. By utilizing Raman scattering, it maintains a stable solid-state laser structure while delivering clinically sufficient energy, earning recognition for solving a challenge that the global laser engineering industry had been unable to resolve for decades using domestic technology.
This device adopts the 589nm wavelength, which has high absorption in intravascular oxyhemoglobin, enabling selective energy delivery to the target blood vessels. As a result, it is presented as a solution that simultaneously pursues high treatment efficacy and safety for various vascular skin lesions, including port-wine stains, hemangiomas, telangiectasia, and rosacea.
The Vascula 589 utilizes the Quasi-long Pulse (QLP) method. It supports a wide range of pulse widths from 0.5 ms to 40 ms, allowing heat to accumulate gradually according to the size and depth of the lesion. This design ensures stable energy delivery while minimizing tissue damage. It also features high-speed repetition at up to 10 Hz and support for various spot sizes to reduce procedure time, and is equipped with a CSC cooling system to protect the epidermis and enhance patient comfort during treatment.
The KGW Raman laser technology underlying the Vascula 589 was published in the international journal *Applied Sciences* (MDPI), where its technical originality and scientific validity were recognized, and related patent applications have been filed. Developed with support from the Ministry of SMEs and Startups’ Small and Medium Enterprise Innovation Development Project, this device is regarded as a model of public-private cooperation that promises both high-value-added technological self-reliance and import substitution in the domestic market, which has historically relied heavily on imports in the vascular laser sector.
Lee Chang-jin, CEO of Laser Optic, stated, “The Vascula 589 is a symbolic product that solves the long-standing challenge of achieving high-power 589nm output based on solid-state lasers using our proprietary technology,” adding, “We will set a new standard in the global market for the treatment of vascular skin diseases and demonstrate the leadership of Korean medical laser technology on the world stage.”
