在激光的医疗应用方面，特别是在过去的十年里，已经发展了一个新的子专业，这取决于激光的治疗应用而不是外科应用。激光疗法，或最好是低反应性激光疗法(LLLT)现在被认为是一种有效的医疗工具。提出了两种类型的LLLT：同步LLLT和纯LLLT。在外科激光应用中，在目标组织中产生一定范围的热量，破坏或改变其结构。这被称为高反应性激光治疗，或HLLT。此外，还可能发生非光热破坏性反应，如光渗透反应。这些也是HLLT的一部分。同时，非破坏性的热和非热的生物激活发生在目标组织的外围：这是“同时的LLLT”，与HLLT一起发生，解释了激光手术的一些优点。已经开发了激光系统，其提供的功率和能量密度低于破坏性水平，仅用于激活受照射的组织。这是“纯粹的LLLT”介绍了LLLT的历史和背景，讨论了LLLT的术语，并介绍了LLLT的实际应用。
A new subspecialty in the medical application of the laser has developed, especially over the last decade, depending on the therapeutic rather than the surgical applications of the laser. Laser therapy, or preferably, Low reactive-Level Laser Therapy (LLLT) is now being recognized as a valid medical tool. Two types of LLLT are presented, simultaneous and pure. In surgical laser applications, ranges of heat are generated in the target tissue, destroying or altering its architecture. This is referred to as high reactive-level laser treatment, or HLLT. In addition, nonphotothermally destructive reactions may also occur, such as photo-osmosis. These are also part of HLLT. Simultaneously, nondestructive thermal and nonthermal bioactivation occur at the periphery of the target tissue: this is "simultaneous LLLT" and occurs along with HLLT, explaining some of the advantages of laser surgery. Laser systems have been developed which deliver power and energy densities below the destructive level, only to activate the irradiated tissue. This is "pure LLLT." The history and background of LLLT are presented, the terminology discussed, and practical applications of LLLT are presented.
