Simultaneous determination of gain parameters in steady state lasers

Description: The optical gain parameters of pulsed steady-state lasers, such as dye and excimer lasers, are determined from a single set of experiments from either a laser oscillator or an amplifier. The gain parameters determined by this technique are the small-signal gain coefficient, the saturation intensity for stimulated emission, the saturation fluence for stimulated emission, and the non-saturable absorption coefficient. The measured saturation properties of laser amplifiers and oscillators are used in a data fitting routine that finds all of the gain parameters simultaneously. The values of the gain parameters are determined with greater accuracy than by the conventional methods of measuring each of the parameters individually. The knowledge of the values of all the gain parameters allows for the determination of fluorescence lifetime of a gain medium.

Battlefield laser wavemeter

Description: In this paper we present a summary of the specifications and architecture for a ruggedized laser wavemeter. This wavemeter is about the size of a pocket calculator and has a wavelength resolution of one part per million. The detectable wavelength range is from the near infrared to the near ultraviolet. The wavemeter is specifically designed to distinguish laser threats from incoherent light sources and measure multiple wavelengths simultaneously. The information update rate is greater than ten readings per second. 1 fig.

Amchitka Island Environmental Analysis at Idaho National Laboratory

Description: The Idaho National Laboratory (INL) provided support to Consortium for Risk Evaluation with Stakeholder Participation (CRESP) in their activities which is supported by the Department of Energy (DOE) to assess the impact of past nuclear testing at Amchitka Island on the ecosystemof the island and surrounding ocean. INL participated in this project in three phases, Phase 1, Phase 2 and Phase 3.
