With this award from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at the University of Wisconsin in La Crosse will acquire a three-laser heterodyne frequency measurement system. The measurement system will allow the investigators to measure the wavelengths, frequencies and characteristics (relative intensity, frequency offset and polarization) of newly discovered laser emissions in the far infrared region. This equipment will then be used in conjunction with an existing optically pumped molecular laser (OPML) and Stark spectrometer. With this enhanced laser system, the principal investigators will investigate molecules that are currently of interstellar and atmospheric interest. The addition of new laser emissions greatly enhances the scope of optically pumped molecular lasers. By opening up the short-wavelength portion of the electromagnetic spectrum, complete coverage of the entire far infrared region is accomplished and a number of spectroscopic techniques will benefit. These studies will involve the active participation of undergraduates at the University of Wisconsin-LaCrosse.

凭借重大研究仪器 (MRI) 计划的这一奖项，位于拉克罗斯的威斯康星大学化学系将获得一套三激光外差频率测量系统。 该测量系统将使研究人员能够测量新发现的远红外区域激光发射的波长、频率和特性（相对强度、频率偏移和偏振）。 该设备随后将与现有的光泵分子激光器 (OPML) 和斯塔克光谱仪结合使用。 借助这种增强型激光系统，主要研究人员将研究目前对星际和大气感兴趣的分子。 新激光发射的加入极大地增强了光泵分子激光器的范围。 通过开放电磁波谱的短波长部分，可以实现整个远红外区域的完全覆盖，并且许多光谱技术将受益。 这些研究将涉及威斯康星大学曲棍球大学本科生的积极参与。
