what happen if the the laser 10 time bigger....

As in other diodes, when this structure is forward biased, holes from the p-region are injected into the n-region, where electrons are the majority carrier.   more...Similarly, electrons from the n-region are injected into the p-region, where holes are the majority carrier. When an electron and a hole are present in the same region, they may recombine by spontaneous emission—that is, the electron may re-occupy the energy state of the hole, emitting a photon with energy equal to the difference between the electron and hole states involved. These injected electrons and holes represent the injection current of the diode, and spontaneous emission gives the laser diode below lasing threshold similar properties to an LED. Spontaneous emission is necessary to initiate laser oscillation, but it is a source of inefficiency once the laser is oscillating.  less

Wow.... That Scary

Waste, rubbish, trash, garbage, or junk is unwanted or undesired material. "Waste" is the general term; though the other terms are used loosely as synonyms, they have more   more...specific meanings: rubbish or trash are mixed household waste including paper and packaging; food waste or garbage (North America) is kitchen and table waste; and junk or scrap is metallic or industrial material. There are other categories of waste as well: sewage, ash, manure, and plant materials from garden operations, including grass cuttings, fallen leaves, and pruned branches.Though the cleanliness of public streets has long been a public responsibility, it was only towards the end of the 19th century that waste collection and disposal began to be considered part of the public health and sanitation function of municipalities.  less
