We experimentally study two Ti:sapphire optical frequency comb femtosecond regimes, respectively, with a linear and a nonlinear dependence of the carrier-envelope offset frequency (f CEO ) on pump intensity. For both regimes, we study the effect of single-and multimode pump lasers on the f CEO phase noise. We demonstrate that the femtosecond regime is playing a more important role on the f CEO phase noise and stability than the pump laser type.

“…6 This means that the LD regime has a higher orthogonality between f rep and f CEO with respect to the TPD regime. This corresponds to ν L 0 ≈ 1.47 THz, that is, two orders of magnitude fewer than the fixed point value we measured in the TPD case: ∼147 THz.…”

“…The FFC consists of a femtosecond seed laser, an optical spectrum broadening system for its emission and an output frequency stabilization system. Solid-state lasers based on Ti:Sa [8,9], Cr:F [10,11] and Yb [12] crystals can be used as reference lasers. Currently, the most promising FFCs are erbium fiber lasers [13][14][15].…”

A study of the influence of temperature fluctuations of individual blocks of a fiber femtosecond frequency comb (FFC) generator and of the entire system as a whole on its output radio frequencies has been carried out. A two-circuit system for thermal stabilization of the air inside the FFC housing was implemented. An additional system for thermal stabilization of the transport fiber, which is included in the measurement scheme (outside the FFC), was implemented. A significant temperature effect on the measured output frequencies of the FFS is shown. Thanks to all the thermal stabilization systems, it has been shown that the instability of the developed fiber FFC introduced into its output microwave frequencies (in addition to the instability of the reference optical standard) is no worse than 2 × 10−16 per 1000 s.

“…While modelocked Yb:fiber lasers are available at repetition frequencies approaching 1 GHz [7], achieving pulses with the sufficiently short durations and high peak powers needed to generate a coherent octave-spanning spectrum becomes very difficult; conversely, the power per comb mode increases with higher repetition rates, implying that an approach based on a linear stabilization technique should be favorable. Heterodyne beats between stabilized CW lasers and adjacent comb teeth have previously been used to lock the offset frequency of Ti:sapphire combs using a 1064-nm iodine-referenced Nd:YAG laser [8], a 822-nm cesiumreferenced external cavity diode laser (ECDL) [9], a 3.39-µm methane-referenced HeNe laser [10] and a 698-nm cavity-stabilized ECDL [11]. Similar techniques were used to stabilize Er:fiber combs to a 780-nm Rb-referenced ECDL [12] and to two Rb resonances based on electromagnetically induced transparency absorption and two-photon absorption [13].…”

The comb spacing was referenced to a Rb-stabilized microwave synthesizer and the comb offset was stabilized by generating a super-continuum containing a coherent component at 780.2 nm which was heterodyned with a 87 Rb-stabilized external cavity diode laser to produce a radio-frequency beat used to actuate the carrier-envelope offset frequency of the Yb-fiber laser. The two-sample frequency deviation of the locked comb was 235 kHz for an averaging time of 50 seconds, and the comb remained locked for over 60 minutes with a root mean squared deviation of 236 kHz.
