A strained saturable Bragg reflector (SSBR) for passive mode-locking of Ti:sapphire lasers was investigated by the frequency resolved optical gating (FROG) technique. Incident pulses of several wavelengths and with zero, positive, or negative chirp were employed. A considerable pulse shortening near the excitonic resonance of the strained quantum well was observed and attributed to anomalous dispersion due to resonance absorption. On the long wavelength side of exciton resonance, however, the chirp of the reflected pulse showed a weak wavelength dependence attributed to the material dispersion of SSBR in pulse broadening was obtained.

“…[1][2][3] For high-peak-power applications, passively mode-locked lasers are generally more desirable than active ones because of their simpler cavity setup and shorter pulse width. Owing to the successful development of semiconductor saturable absorber mirrors ͑SESAMs͒ 4 and saturable Bragg reflectors ͑SBRs͒, 5,6 self-starting passive mode locking of a variety of diode-pumped solid-state lasers have been demonstrated. 7 The advantages of these semiconductor-based saturable absorbers are their low saturation energies, their compact design, and the possibility of engineering the absorber for particular laser systems, e.g., dispersion compensation.…”

“…8 Three strained InAlGaAs quantum wells with separated but sequential absorption peaks at adjacent wavelengths were deposited to extend the absorption linewidth. 2,9,10 The output power, pulse width, and repetition rate of the Ti:sapphire SBR laser at a pump power of 5 W ͑with an all-line largeframe argon-ion laser; Coherent Innova 400͒ are 250 mW, Ͻ100 fs, and 85 MHz, respectively. The Ti: sapphire rod and the SBR were both temperature regulated for control of the residual thermal fluctuation below 0.1°C.…”

Piezoelectric-transducer-based optoelectronic frequency synchronizer for control of pulse delay in a femtosecond passively mode-locked Ti:sapphire laser

We propose a piezoelectric transducer-(PZT-) based optoelectronic frequency synchronizer to control simultaneously change in the repetition rate, the relative pulse delay, and the phase noise of a passively mode-locked femtosecond Ti:sapphire laser with an intracavity saturable Bragg reflector absorber with respect to an electronic frequency reference. An optoelectronic phase-locked-loop-based PZT feedback controller with a proportional, integral, and differential (PID) circuit and a tunable voltage regulator is designed to achieve frequency synchronization, phase-noise suppression, and delay-time tuning. When the controlling voltage is tuned from -2.6 to 2.6 V, the maximum pulse-delay range, tuning slope, and tuning resolution of the laser pulse-train are 11.3 ns, 2.3 ps/mV, and 1.2 ps, respectively. Setting the gain constant of the PID circuit at 10 or larger causes the delay-time tuning function to be linearly proportional to the controlling voltage. In the delay-time tuning mode the uncorrelated single-side-band phase-noise density of the frequency-synchronized laser is approximately -120 dBc/Hz at an offset frequency of 5 kHz, which is only 7 dBc/Hz higher than that of the electrical frequency reference. The proposed system also supports linear,continuous switching,and programmable control of the delay time of Ti:sapphire laser pulses when they are frequency synchronized to external reference clocks.
