This report outlines the most essential characteristics of low power lasers commonly used in physical medicine. The optical output power of two Helium-Neon (HeNe) lasers (CW scanner) and two collimated Infrared (IR) laser diodes was measured with a CoherentR Model 212 meter designed to measure output power and its power density. The energy of two collimated IR lasers was measured with a Laser Precision Energy Meter equipped with an RJP-735 probe. The difficulties arising from the large divergence of the laser beam in diode lasers and the importance of the scattering and absorption of laser beams are discussed. The criteria for the evaluation of the lasers as well as the essential parameters for an adequate characterization of laser therapy are given.
本报告概述了物理医学中常用的低功率激光器的最基本特性。使用一台设计用于测量输出功率及其功率密度的相干R型212米测量仪，测量了两台氦氖（HeNe）激光器（连续波扫描仪）和两台准直红外（IR）激光二极管的光输出功率。使用配备RJP - 735探头的激光精密能量计测量了两台准直红外激光器的能量。讨论了二极管激光器中激光束发散度大所带来的困难以及激光束散射和吸收的重要性。给出了激光器评估标准以及充分表征激光治疗的基本参数。
