A laser transmitter has been developed and incorporated into a micro-pulse differential absorption lidar (DIAL) for water vapor profiling in the lower troposphere as an important step towards long-term autonomous field operation. The laser transmitter utilizes two distributed Bragg reflector (DBR) diode lasers to injection seed a pulsed tapered semiconductor optical amplifier (TSOA). ... https://www.roneverhart.com/Verragio-Paradiso-Round-Diamond-Engagement-Ring-Setting-0-55-CTW-p5464/
