Ultrasensitive spectroscopy, the ultrastable lasers, the ultrafastlasers, and the seriously nonlinear fiber: a new alliance for physicsand metrology

摘要

We now appreciate the fruit of decades of development in thenindependent fields of ultrasensitive spectroscopy, ultrastable lasers,nultrafast lasers, and nonlinear optics. But a new feature of the pastntwo or three years is the explosion of interconnectedness between thesenfields, opening remarkable and unexpected progress in each, due tonadvances in the other fields. For brevity, we here focus mainly on thennew possibilities in the field of optical frequency measurement
