Fiber laser oscillators are the type of electronic oscillators that use crystal to select the particular frequency so that the inverse piezoelectric effect is obtained. It uses the vibrating crystal so that the mechanical resonance is used from it, having piezoelectric properties so that an electric signal of high precise frequency is obtained. The frequency so obtained is also used in keeping track of time, to stabilize frequencies for receivers and radio transmitters. A similar crystal called quartz crystal can also be used to obtain frequencies from kilohertz to few megahertz. These crystals are used for devices such as radios, computers, clocks, cell phones and wrist watches. Quartz crystal can also be found in measurement and test equipment such as oscilloscopes, signal generators, and counters. Temperature compensated oscillator is the dominating equipment in the market finding its use in the networking and telecom industry. The oven controlled oscillator is also expected...
