Undergraduate Laser Laboratory

激光是许多科学领域不可缺少的工具 与工程学阿拉斯加大学，费尔班克斯（UAF）是 提供一个全面的，本科水平，一学期 激光实验室课程，遵循现有的一个学期 经典光学课程（带实验室）。过去几 多年来，UAF积累了各种激光器， 激光实验室特别是，我们有氩离子激光器， 闪光灯泵浦的染料激光器，氮激光器，氮激光器， 泵浦染料激光器，一些氦氖激光器，和一个Nd：YAG 激光。该项目正在获得最终的仪器， 将使我们能够为学生提供这门课程。 在 特别是，我们正在获得：校准焦耳计， 测量各种脉冲激光器中的脉冲能量;二极管 光栅光谱仪的阵列，这样我们就可以测量激光 光谱“单次发射”;另一个二极管阵列测量空间 光束轮廓;一个二极管激光器来填补我们的激光器中的一个洞 一个带布鲁斯特窗的氦氖管和一套 这样学生们就能体验到 对准几个不同的腔（共焦， 半球形和平坦平坦）;数据 记录仪，以便我们可以使用我们的扫描光栅光谱仪（与 光电倍增管）来测量脉冲的调谐曲线 氮激光泵浦染料激光器，一组输出耦合器， 氩离子激光器的透射率范围，使得 学生可以看到514 nm线之间的增益差异， 和488纳米线;和几副安全护目镜， 学生可以安全地使用Nd：YAG激光器。鉴于 激光在当代科学中的重要性 我们的学生通过提供这门课程提供了很好的服务， 他们选择去读研究生或进入就业市场 立即

The laser is an indispensable tool in many fields of science and engineering. The University of Alaska, Fairbanks (UAF) is providing a comprehensive, undergraduate-level, one-semester laser laboratory course which follows an existing one-semester course in classical optics (with lab). Over the last several years UAF has accumulated a wide variety of lasers for the laser lab. In particular, we have an Argon ion laser, a flashlamp-pumped dye laser, a nitrogen laser, a nitrogen laser- pumped dye laser, a number of helium-neon lasers, and a Nd:YAG laser.This project is obtaining the final instruments which will allow us to offer this course to our students. In particular, we are obtaining: a calibrated Joule meter to measure the pulse energy in the various pulsed lasers; a diode array for our grating spectrometer so we can measure laser spectra "single shot;" another diode array to measure spatial beam profiles; a diode laser to fill a hole in our laser inventory; a helium-neon tube with Brewster windows and a set of external mirrors so that the students can get the experience of aligning several different cavities (confocal, hemispherical, and flat-flat) for a fixed gain medium; a data logger so we can use our scanning grating spectrometer (with photomultiplier tube) to measure the tuning curve of the pulsed nitrogen laser-pumped dye laser, a set of output couplers with a range of transmittances for the Argon ion laser so that the students can see the difference in gain between the 514 nm line and the 488 nm line; and several pairs of safety goggles so that the students can safely use the Nd:YAG laser.Given the importance of the laser in contemporary science we are doing our students a great service by providing this course whether they choose to go to graduate school or enter the job market immediately.
