Pressure and power broadening of the a(10) component of R(56) 32-0 transition of molecular iodine at 532 mn

Abstract

We determine the linewidth of the hyperfine structure a(10) component of R(56) 32-0 transition of I-127(2) at 532 nm using the dependence of the peak amplitude of the third-derivative signal on the modulation width. We also use the same method to investigate pressure broadening and power broadening of the a(10) component. (c) 2005 Elsevier B.V. All rights reserved.
