“…A commonly used combination of actuators to accomplish this is a fast intracavity EOM [68][69][70][71][72][73][74] for cavity length changes, with fixed point near DC (n * ∼ 0), and the pump laser power for changing the intracavity pulse's round trip phase shift, with fixed point near the optical carrier frequency. 53,57,75 While fast bandwidth can be obtained via actuating on the pump current in some laser designs, 61 the bandwidth attainable with this actuator depends on the details of the laser and population inversion dynamics. 76 In the current ring cavity design with lower loss and smaller gain than the laser in reference 61, and thus lower relaxation oscillation frequency, we have observed the bandwidth of pump power modulation to be quite limited, as shown in figure 3a).…”

We present a detailed description of the design, construction, and performance of high-power ultrafast Yb:fiber laser frequency combs in operation in our laboratory. We discuss two such laser systems: an 87 MHz, 9 W, 85 fs laser operating at 1060 nm and an 87 MHz, 80 W, 155 fs laser operating at 1035 nm. Both are constructed using low-cost, commercially available components, and can be assembled using only basic tools for cleaving and splicing single-mode fibers. We describe practical methods for achieving and characterizing low-noise single-pulse operation and long-term stability from Yb:fiber oscillators based on nonlinear polarization evolution. Stabilization of the combs using a variety of transducers, including a new method for tuning the carrier-envelope offset frequency, is discussed. High average power is achieved through chirped-pulse amplification in simple fiber amplifiers based on double-clad photonic crystal fibers. We describe the use of these combs in several applications, including ultrasensitive femtosecond time-resolved spectroscopy and cavity-enhanced high-order harmonic generation. C 2016 Author(s).

“…High-quality OFC with a large number of comb lines, high flatness of comb line power, and tunable frequency spacing is the current research focus. OFC can be generated based on mode-locked laser [6,7], nonlinear fiber [8], micro-ring resonator [9], photoelectric oscillator [10,11], and external modulator [12][13][14][15][16][17][18][19]. Among these methods, using external modulator has the advantages of stable output spectrum, adjustable frequency spacing between comb lines, simple structure, and flexible operation.…”

Broadband optical frequency comb (OFC) generation based on a single electro-absorption modulator (EAM) is proposed. The EAM is driven by a radio frequency (RF) multi-frequency signal generated by a multiplication coupler composed of an electrical power splitter and an arithmetic circuit. Thus the number of comb-lines of the generated OFC can be increased. A complete theoretical model of OFC generation by an EAM driven by nth power of the RF source is established, and the performance of the OFC is analyzed by using OptiSystem software. The results show that, the number of comb-lines of the OFC is positively correlated with the number of multiplication of the RF source signal. The frequency spacing of the comb-lines is twice the frequency of the RF source signal and is tunable by adjusting the frequency of the RF source signal. Increasing chirp factor and modulation index of EAM could increase the number of comb-lines of the generated OFC. The amplitude of the RF source signal had little impact on the flatness of the OFC and the average OFC power. The scheme developed is not only simple and low-cost, but also can produce a large number of comb-lines. Graphical Abstract

“…These generation techniques can be generally categorized into six main types. The two classical ones are based on mode-locked lasers (MLLs) [11,12] and on cyclic frequency shift structures [13,14]. The four others can all be classified into the microwave photonic domain, namely, based on modulators [15,16], based on optoelectronic oscillators (OEOs) [17,18], based on nonlinear optical fibers [19,20], and based on optically injected semiconductor lasers [21,22].…”

Robust Optical Frequency Comb Generation by Using a Three-Stage Optical Nonlinear Dynamic

et al. 2021

View full text Add to dashboard Cite

In this article, we propose and investigate a novel scheme to generate optical frequency combs (OFCs) by using a three-stage generator, which is based on optical injection–induced dynamics cascaded by subharmonic electro-optic modulation and the four-wave mixing (FWM) effect. A primary seed OFC is rooted from the nonlinear dynamics in the optically injected semiconductor laser, and its performance is improved using a two-stage booster based on subharmonic electro-optic modulation and the FWM effect. The comb spacing can be easily tuned by adjusting that of the primary seed OFC or through electro-optic modulation by the use of subharmonics with different orders. Moreover, it becomes stabilized because the phase relationship between the comb teeth can be fixed in the process of subharmonic electro-optic modulation. Its optical spectrum continues to be broadened in the following FWM process. Finally, robust OFCs with a comb spacing of 4 GHz and a comb teeth number of 23 and a comb spacing of 5 GHz and a comb teeth number of 21 are experimentally demonstrated.
