How to dismantle equipment from a communication tower

In this video we show you how to dismantle a concrete telecommunications tower with a crane truck. Every health and safety measures at work were strictly comp. PTTG has experienced crews available to help when owners determine they no longer need their tanks, towers, or other structures and require them to be dismantled and removed, including scrap disposal and site cleanup. On occasion, tanks or towers cease to function or become too old to maintain. This can include towers, batteries, internal equipment, hazardous material, and communication shelter removal. We handle each project with safety and sticking to a budget in mind. Cellular tower demolition jobs can be trickier than most jobs. Legalities of what third parties have access to the site can cause issues–issues we will take care of. Our experienced team handles all aspects of decommissioning, including: • Mount & Antenna Removal – Dismantling old equipment with precision. • Microwave Decommissioning – Safely uninstalling. [PDF]

Laser Diodes and Semiconductor Lasers

As diode lasers are semiconductor devices, they may also be classified as semiconductor lasers. Either designation distinguishes diode lasers from solid-state lasers.OverviewA laser diode (LD, also injection laser diode or ILD or semiconductor laser or diode laser) is a device similar to a in which a diode pumped directly with electrical current can create. A laser diode is electrically a. The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectivel. Following theoretical treatments of M.G. Bernard, G. Duraffourg, and William P. Dumke in the early 1960s, light emission from a (GaAs) semiconductor diode (a laser diode) was demonstrat. [PDF]
