Future Electronics May Depend on Lasers, Not Quartz
Pasadena CA (SPX) Jul 22, 2014 - Nearly all electronics require devices called oscillators that create precise frequencies-frequencies used to keep time in wristwatches or to transmit reliable signals to radios. For nearly 100 years, these oscillators have relied upon quartz crystals to provide a frequency reference, much like a tuning fork is used as a reference to tune a piano. However, future high-end navigation system ... more
