industry, medicine and other areas of contemporary life. The essential ingredients of a laser are a material that amplifies light through stimulated emission (the gain medium) and a cavity that traps light in the gain medium to enable more efficient amplification. The gain medium is pumped electrically, by a source current, or optically, by another laser source or a lamp. The most common laser cavity is the Fabry-Pérot, made of two mirrors (one of which is partially transmitting) that face each… CONTINUE READING
