Characteristics of RF Excited CO2 Lasers.

OPTIMAL NOZZLE SHAPES OF CO2-N2-H2O GASDYNAMIC LASERS

In an axisymmetric CO2-N2-H2O gas dynamic laser, let ? denote the intersection of the vertical plane of symmetry with the upper part of the (supersonic) nozzle. To obtain a maximal small signal gain, some authors have tested several families of curves for ?. To find the most general solution for ?, an application of Pontryagin’s principle led to the conjuncture that the optimal ? must consist o...

Modeling the Discharge Loading of Radio Frequency Excited Co2 Slab Lasers

Synchrotron Radiation/lasers and Doubly-excited Atoms

This report highlights a series of joint theoretical and experimental collaborations which started over ten years ago in Taiwan. The recent topic program Synchrotron Radiation and Multiply-excited Atoms, sponsored by the National Center for Theoretical Sciences (NCTS) at Tsinghua University in Hsinchu and organized by K. T. Chung and C. S. Hsu, o®ers an excellent opportunity for many of us to w...

Optical pumping of helium with arc lamp excited LNA lasers

2014 We have developed a compact and relatively inexpensive laser source at 03BB =1.083 03BCm, suitable for optical pumping in helium. The laser is made of an LNA crystal transversely pumped by krypton arc lamps. A cw power of 800 mW has been achieved at 1.083 03BCm with a 3 GHz bandwidth. A 66 % nuclear polarization has been obtained in a 3He gas. Revue Phys. Appl. 24 (1989) 827-831 AOÛT 1989,
