Here we describe the structure of two types of quantum spin laser form type quantum dots and wells according to the bucket model. Then, with according to the structures, we study the laser equations first in the conventional state, then we propagate the spin state to better gain. That is, carriers and photons density, with according to the optical gain in both the conventional and spin states, is ratio to time. In the end, we examine the system in a steady state for a state not captured (τc=0ps) and after passing (τc=2ps), which is captured and photons produced.
This paper describes our first undergraduate project experience, final report and findings on the subject matter. Initially according to our project title, we were focused on developing a low cost detector which can detect radiation only. To make one of these kinds of detector doesn’t take much and can be prepared at fairly low cost being very common project in nuclear science arena. The Geiger-Muller tube, or GM tube, is an extremely useful and inexpensive way to detect radiation. While the GM tube can only detect the presence and intensity of radiation, this is often all that is needed.
