Comparative extreme ultraviolet emission measurements for lithium and tin laser plasmas

Detailed spectroscopic studies on extreme UV emission from laser plasmas using tin and lithium planar solid targets were completed. At 13.5 nm, the best conversion efficiency (CE) for lithium was found to be 2.2% at intensities near 7 x 10(10) W/cm(2). The highest CE measured for tin was near 5.0% at an intensity close to 1 x 10(11) W/cm(2).     

Laser nuclear studies

The ability of optical pumping to produce nuclear orientation and the advent of single frequency tunable dye lasers has brought about a new interesting area of study, Laser Induced Nuclear Orientation (LINO). The impact of LINO on the nuclear structure studies of short lived nuclei along with a discussion on various relaxation mechanisms involved are presented. As an example, recent experimental results on^85mRb (T_1/2=1.0 μs) are given in detail. Possible application of LINO to¹⁵¹Eu discussed.
