Sub-kHz Linewidth GaSb Semiconductor Diode Lasers Operating Near 2 Micrometers
We report on the phase noise properties of DFB lasers operating near 2.0 microns. Measured noise spectra indicate intrinsic laser linewidths below 1 kHz. An effective linewidth of less than 200 kHz for 5 ms measurement times is estimated.

Biological Research in Canisters (BRIC) - Light Emitting Diode (LED)
The Biological Research in Canisters - LED (BRIC-LED) is a biological research system that is being designed to complement the capabilities of the existing BRIC-Petri Dish Fixation Unit (PDFU) for the Space Life and Physical Sciences (SLPS) Program. A diverse range of organisms can be supported, including plant seedlings, callus cultures, Caenorhabditis elegans, microbes, and others. In the event of a launch scrub, the entire assembly can be replaced with an identical back-up unit containing freshly loaded specimens.

Hydrazine Detection with a Tunable Diode Laser Spectrometer
Several instruments have been developed to measure low concentrations of hydrazine but none are completely satisfactory. A brief review is presented of current instruments such as the electrochemical cell, the ion mobility spectrometer, the mass spectrometer, the gas chromatograph, and the electronic nose.

A Theoretical Analysis of Steady-State Photocurrents in Simple Silicon Diodes
Funneling under steady-state conditions is investigated, because this problem is simple enough to be treated rigorously and provides some qualitative insights into the more difficult transient problem.
