The Q-switched ruby laser (694 nm, 25-40 nsec) is an effective and safe therapeutic device for the treatment of tattoos and well-defined, benign, pigmented epidermal and dermal lesions. Because of its selective mode of action, dermal pigments of natural and artificial origin are destroyed photothermically and removed without scar. This method is exceptionally suited for the elimination of lay and professional tattoos, traumatic tattoos, and permanent makeup. Other frequent indications include benign pigmented lesions such as lentigines, freckles, café-au-lait spots, seborrheic keratosis, and Becker nevi. As a dermal pigmented lesion, the nevus of Ota is perfectly treatable. However, chloasma can no longer be considered an indication for ruby laser treatment due to unsatisfactory results. Melanocytic nevi and congenital nevi should be treated only in clinical studies. The effectiveness of the long-term epilation of dark hair with this laser device has to be verified in future investigations. Particularly attractive is the nonproblematic and straightforward removal of pigmented lesions in precarious anatomic regions like the lips, eyelids, and genitals (e.g., benign melanosis of the lips or of the penis, seborrheic keratosis of the lid angle).
调Q红宝石激光（694纳米，25 - 40纳秒）是一种有效且安全的治疗设备，用于治疗纹身以及界限清晰的良性色素性表皮和真皮病变。由于其选择性作用模式，天然和人工来源的真皮色素会被光热破坏并去除，不留疤痕。这种方法特别适合消除业余和专业纹身、外伤性纹身以及纹眉。其他常见适应症包括良性色素性病变，如雀斑样痣、雀斑、咖啡斑、脂溢性角化病和贝克痣。作为一种真皮色素性病变，太田痣完全可以治疗。然而，由于效果不理想，黄褐斑不再被视为红宝石激光治疗的适应症。黑素细胞痣和先天性痣仅应在临床研究中进行治疗。该激光设备对深色毛发进行长期脱毛的有效性有待未来研究验证。特别吸引人的是，在诸如嘴唇、眼睑和生殖器等危险解剖区域（如唇部或阴茎的良性黑变病、睑角的脂溢性角化病）去除色素性病变毫无问题且操作简便。
