    Continuous-wave (CW) lasers have been commonly used for endovenous laser ablation (EVLA). However, as some undesired side effects such as postoperative pain and bruising occasionally happens, longer laser wavelength and specially-fabricated laser fibers have been developed. On the other hand, the pulsed-wave (PW) laser, which has a heat production control by thermal relaxation, is independently developed for EVLA. This article discusses the implication of PW laser in EVLA from a theoretical point of view and a newly-developed micropulsation (MP) is introduced as a new concept. Since the MP yields adequate blood and vein wall heat degeneration by microseconds laser emission, efficacy and safety are improved compared with CW laser or conventional PW laser. Initial clinical outcome is favorable and promising for painless EVLA using inexpensive bare fiber.
