“…a mismatch of ¦11 kHz), as a result of the modulator's driving frequency and the cavity's repetition rate no longer coinciding, the pulse essentially passes through the modulator at different temporal locations each round trip, and we do not obtain standard ML; beyond this point, the pulses drop out. These results confirm the predicted theoretical trend in AM-ML detuning [72], in this ML setup we have both a relatively low modulation bandwidth and a relatively high modulation depth, and both effects induce this relatively high tolerance to frequency detuning. The intensity of the reflection sidebands of the AOSLM can be dynamically controlled by varying the voltage applied to the piezoelectric, as we explained before in Sect.…”

“…Detuning is mathematically defined as the frequency shift from the ideal ML frequency. Theoretical studies of detuning in AM ML concluded that the higher the bandwidth and lower the modulation depth, the lower the detuning the laser can tolerate [72]. In this setup, the adjustment between the frequency of the RF signal applied to the piezoelectric and the cavity round-trip did not require a high accuracy.…”

The interest in all-fiber lasers is stimulated by the inherent advantages they have over bulk lasers in aspects such as heat dissipation and robustness. The performance of Q-switched and modelocked fiber lasers can benefit enormously from the development of all-fiber configurations. A fiber laser with strictly all-fiber components can fulfil the requirements of mechanical stability, low maintenance, enhanced power efficiency, simplified assembly process, and low cost. In this framework, recent developments infiber acousto-optic devices are reviewed that have demonstrated new possibilities for actively Q-switched distributed feedback fiber lasers, modelocking lasers and doubly active Q-switched modelocked lasers. The aim is to demonstrate the great potential of infiber devices for the active control of different types of fiber lasers.

“…If we assume for the output pulses of this laser a Gaussian envelope, then this parameter alone determines a lower limit for the pulse width around 0.315/909 MHz=346 ps. On the other hand, the modulator bandwidth (plus the modulation depth and cavity length) also influences the tolerance to frequency detuning in AM mode-locking [35]. In a few words the narrower the modulation bandwidth, the higher the locking range.…”

Mode-locked Yb-doped all-fiber laser based on in-fiber acoustooptic modulation

et al. 2011

Abstract:We show what we believe is the first demonstration of an ytterbium-doped strictly all-fiber active mode-locking laser. The active control of the laser is based on in-fiber amplitude modulation at 11 MHz, which is achieved by using an all-fiber acoustooptic superlattice modulator driven by standing acoustic waves. In our experiments, the laser was operated at 1091.3 nm and had two stable regimes producing either a train of mode-locked single pulses or a train of pulse pairs. Best results for the mode-locked train of single pulses were 740 ps of time width and 26 mW of average power, at a pump power of 480 mW.

“…The modulation depth is a parameter related to the maximum and minimum reflectivity R max and R min of the side lobe calculated as (R max − R min )/R max [10]. An increase in modulation depth reduces the pulse width [28], which is obtained by the application of high powers to the PZT, an improvement of the modulator design or the use of SCFs with larger air holes. However, the maximum modulation depth achieved for the proposed modulator is about 11 dB as shown in figure 3.…”

Acousto-optic modulation of a fiber Bragg grating in suspended core fiber for mode-locked all-fiber lasers

et al. 2015

The interaction of a fiber Bragg grating and longitudinal acoustic waves in a three-airholes suspended core fiber is experimentally investigated and employed to mode-lock an ytterbium-doped fiber laser. An optimized design of an acousto-optic modulator based on two piezoelectric transducers and 1 cm grating length is also proposed. For an electrical signal strength of 10 V applied to the modulator, the results indicate output pulses with a width of less than 550 ps at a repetition rate of 10 MHz. The reduction of the grating length and the power consumed by the transducer, when compared to previous studies, points out to more efficient, compact and fast acousto-optic modulators for mode-locked all-fiber lasers.
