“…Other work has shown that deionized water absorbs in the 950 to 1100 nm absorption band of Yb and that use of perfluropolyether can improve performance. 9 Diagnostic setups were prepared to measure various characteristics of the free-running oscillator. The following characteristics were measured:…”

We develop a high-power Er:strengthened-glass laser emitting at the eye-safe 1.535 m wavelength. To maximize the output parameters of an Er:glass laser, whose power supply must also be used with Nd:YAG, a two-lamp laser head with parallel power forming networks (PFNs) that could be fired with an internal delay is used. The system operates at a slope efficiency of 0.45%, yielding a maximum pulse energy of 330 mJ. Thermal effects are measured, indicating strong thermal lensing, of 16 diopter/kW and mild birefringence induced depolarization of 5% at 200 W electrical power. From this data we determine the radial-tangential average and birefringence elasto-optical coefficients, C r, ϭ0.075Ϯ0.002 and C B ϭ0.0094, respectively. A TEM 00 beam is achieved for a hemispherical resonator configuration. Based on the measurements, a design is presented for improved high-power TEM 00 performance using principles based on dynamic compensation of thermal focusing and birefringence correction using a reentrant resonator. © 1998 Society of Photo-Optical Instrumentation Engineers.

“…Seasonal changes in pH, dissolved carbon dioxide and total dissolved calcium concentration do affect its availability [2]. It is very important to mention that phosphates and its derivatives also find wide applications in pharmaceutical industries, food industries, lasers and sensor technologies [3][4][5][6] to mention but a few . The need to regulate phosphate use and monitor its concentration in the environment cannot be overstated.…”

Highly selective and sensitive phosphate sensors have been fabricated by constructing a solid membrane disk consisting of variable mixtures of aluminium powder (Al), aluminium phosphate (AlPO 4) and powdered copper (Cu). Both binary and ternary electrode systems are produced. The ternary membranes exhibit greater selectivity over a wide range of concentrations. The ternary electrode with the composition 25% AlPO 4 , 25% Cu and 50% Al was selected as our preferred electrode. The newly fabricated ternary membrane phosphate selective electrodes exhibited linear potential response in the concentration range of 1.0 × 10 í1 to 1.0 × 10 í6 mol L í1. The electrodes also exhibit a fast response time of <60 s. Their detection limit is lower than 1.0 × 10 í6 mol L í1. The unique feature of the described electrodes is their ability to maintain a steady and reproducible response in the absence of an ionic strength control. The electrodes have a long lifetime and can be stored in air when not in use.
