YellowStar® by Asclepion is a next-generation 577 nm HOPSL laser system designed for precise treatment of vascular and pigmented skin conditions and non-invasive improvement of overall skin quality.
Why 577 nm Makes the Difference
The 577 nm wavelength is particularly well suited for vascular applications because it corresponds closely to the absorption maximum of oxyhemoglobin. This enables highly selective interaction with superficial blood vessels while maintaining controlled energy delivery to surrounding tissue.
Compared with wavelengths with greater melanin absorption, 577 nm provides a favorable balance between vascular selectivity and interaction with epidermal pigment, supporting precise treatment across a broad range of dermatological and aesthetic applications.
Short pulse durations combined with increased output power allow precise energy delivery while reducing thermal load, supporting controlled treatment conditions and efficient clinical performance.
Precision Meets Performance
YellowStar® combines increased output power with short, precisely controlled pulses to deliver energy efficiently while limiting unnecessary thermal exposure.
With a maximum output of 8 W, pulse durations from 2 to 150 ms, frequencies from 1 to 100 Hz, and both pulsed and continuous operating modes, the system provides flexibility for different treatment strategies and clinical indications.
Its compact tabletop design combines professional performance with convenient integration into everyday clinical practice.
