The capacitor for the time delay from Power On to Laser On is mounted under the PCB. The parts marked with «*» are to pulse the Enable line on power-up. Midinfrared resonant magnetic nanostructures exhibiting a negative permeability. This isn’t exactly magnet wire but the insulation is still rather thin so it packs nicely. There are two ways around the second problem.
This will then protect against shorts in the cable as well. The dissipation of the controller is relatively low so this probably isn’t needed for it but won’t hurt. Do not overtighten the mounting screws in either case. The mirrors apparently tolerate it better but these also may degrade after awhile.
This module is part of the portable AN/GMQ-33 «Cloud Height Set.» This meteorological instrument is used to determine ceiling height from 100 to 3,000 feet AGL. It runs on a 24 Volt NiCd or LiSO2 battery and is 12″ x 14″ x 13″ and weighs 32 pounds. Alternatively or in addition, current limiting resistors (e.g., 25 ohms or more) can be installed in series with any circuits using the +5 VDC (except Interlock) if they won’t affect functionality of control panel switches and LEDs or other indicators. Some versions of this laser obtained surplus may differ slightly, lacking the collimator, for example. Even if the flash duration is as long as 3 ms, half the time, more than 50 percent of the available energy will have been transferred to the rod when the Q-switch is triggered. The power supply is approximately 4″ x 4″ x 1.5″ and operates from 12 VDC. The laser is somewhat unique in that it is permanently aligned, utilizes a ceramic exoskeleton for stability, and a positive branch confocal resonator design for high beam brightness. Green et al.12 investigated the light-trapping effect using Ag nanoparticles on a 1.25-µm-thick c-Si on an insulator solar cell and reported a broadband enhancement and a 16-fold enhancement at 1050 nm.
