Queensborough Community College is upgrading the laboratory modern optics component of its technology courses by introducing current instrumentation for the study of the lasers. Through laboratory experiments students gain an understanding of the principles and measurement techniques involved in the study and use of high power lasers. The centerpiece of the laboratory is a mode-locked Nd-YAG laser. With the additional of a Q-switch and second harmonic generator, a number of experiments cover the principles of thermal lensing, acousto-optic modulation and mode-locking, Q- switching and non-linear optics (second harmonic generation). Along with aligning the lasers and beam profile measurements, these experiments provide a practical application of many of the principles discussed in optics courses. By using sampling Oscilloscopes and fast photodetectors, students not only observe phenomena normally outside the range of observation but also gain experience with valuable research tools. The experience provides students who are uniquely equipped to either become laser technicians or continue in a four year degree program.

昆斯伯勒社区学院（Queensborough Community College）正在通过引入当前用于激光研究的仪器，升级其技术课程的实验室现代光学部分。通过实验室实验，学生可以了解高功率激光器的研究和使用的原理和测量技术。实验室的核心是一个锁模Nd-YAG激光器。随着Q开关和二次谐波发生器的增加，一些实验涵盖了热透镜、声光调制和锁模、Q开关和非线性光学（二次谐波产生）的原理。随着对准激光和光束轮廓测量，这些实验提供了许多在光学课程中讨论的原理的实际应用。通过使用采样示波器和快速光电探测器，学生不仅观察到通常超出观察范围的现象，而且还获得了宝贵的研究工具的经验。这些经验为学生提供了独特的装备，要么成为激光技术人员，要么继续攻读四年制学位课程。
