- 요약Dual-comb technology has revolutionized the field of metrology by harnessing the high accuracy and resolution provided by optical frequency combs. The current direction in dual-comb research strives towards achieving simplified dual-comb systems with low cost and low footprint to make dual-comb technology accessible outside of laboratory setting. Direction multiplexed, single-cavity dual-comb lasers in fiber platform are an attractive low-cost, compact, and robust solution. However, their lower pulse energy compared to traditional techniques necessitates additional amplification stages for practical implementations. Moreover, the traditional dual-comb sources also suffer from an inherent trade-off between temporal resolution and measurement frame rate. In this thesis, we make a significant leap towards democratizing dual-comb technology through the introduction of a novel, high energy counter propagating all-normal dispersion (CANDi) fiber laser with up to 8nJ pulse energy, 190fs pulse duration and tunable repetition rate difference (∆frep) that can reach as low as few Hz. The combination of these characteristics directly enables multitude of high-resolution linear and nonlinear dual-comb applications. The thesis also introduces a ground-breaking, generally applicable, dynamic ∆frep modulation technique to achieve high frame rate in dual-comb metrology preserving the fine temporal resolution of small ∆frep systems such as CANDi. Moreover, a novel relative timing jitter measurement technique with low noise floor, shot-to-shot measurement capability and low optical power requirement is presented in this work that is applicable to even low energy dual-comb systems.The thesis focuses on characterization of the dual-comb performance of CANDi laser and its dynamically modulated counterpart (DCANDi), including their relative timing jitter characteristics and explores pathway for improvement. We demonstrate the versatility of the above systems through application in dual-comb pump-probe experiment and for the first time, as a single-cavity dual-comb source for quantum Hong-Ou-Mandel interference inspired intensity correlation measurements with potential applications in ranging and imaging. The thesis is concluded with the possibility of extending the wavelength range of CANDi laser from near infrared regime to mid infrared and long wavelength infrared regimes to capitalize the rich potential of dual-comb applications in this region.
