“…The semiconductor gain chip enables bandgap engineering to provide a high degree of flexibility in the operation wavelength [9]. Modelocked VECSELs with high-Q cavities have been demonstrated, resulting in a low timing jitter noise [10,11], which is comparable to the noise performance of ion-doped solid-state lasers [12]. This makes them very interesting for optical communication [13] and frequency metrology applications [14,15].…”

Optically pumped vertical-external-cavity surface-emitting lasers (OP-VECSELs), passively modelocked with a semiconductor saturable absorber mirror (SESAM), have generated the highest average output power from any sub-picosecond semiconductor laser. Many applications, including frequency comb synthesis and coherent supercontinuum generation, require pulses in the sub-300-fs regime. A quantitative understanding of the pulse formation mechanism is required in order to reach this regime while maintaining stable, high-average-power performance. We present a numerical model with which we have obtained excellent quantitative agreement with two recent experiments in the femtosecond regime, and we have been able to correctly predict both the observed pulse duration and the output power for the first time. Our numerical model not only confirms the soliton-like pulse formation in the femtosecond regime, but also allows us to develop several clear guidelines to scale the performance toward shorter pulses and higher average output power. In particular, we show that a key VECSEL design parameter is a high gain saturation fluence. By optimizing this parameter, 200-fs pulses with an average output power of more than 1 W should be possible.

The performance of ultrafast semiconductor disk lasers has rapidly advanced in recent decades. The strong interest from industry for inexpensive, compact, and reliable ultrafast laser sources in the picosecond and femtosecond domains has driven this technology toward commercial products. Frequency metrology and biomedical applications would benefit from sub-200-femtosecond pulse durations with peak powers in the kilowatt range. The aim of this review is to briefly describe the market potential and give an overview of the current status of mode-locked semiconductor disk lasers. Particular focus is placed on the ongoing efforts to achieve shorter pulses with higher peak powers.

“…So far only a limited number of studies on timing jitter in semiconductor disk lasers have been published. Rms timing jitter of passively modelocked VECSELs with quantum well SEASAMs with a center wavelength of 1043 nm and 2.3-ps pulses was measured to be 410 fs in the bandwidth of 1 kHz to 15 MHz in a free-running mode and 160 fs with active stabilization [9]. In subsequent experiments with sub-500-fs pulses, timing jitter of 190 fs (from 300 Hz to 1.5 MHz) were demonstrated in a actively stabilized cavity [10].…”

Timing jitter characterization of a quantum dot SESAM modelocked VECSEL

We present timing jitter measurements of a free-running SESAM modelocked VECSEL generating 8-ps pulses with 1.88-GHz repetition rate and 80-mW average output power. We observed very good performance comparable with iondoped solid-state-lasers which typically show excellent stability. We measured the two-sided noise power spectral density at the 10th harmonic of the laser output with the von der Linde method. The rms timing jitter integrated over an offset frequency range from 100 Hz to 100 kHz gives a free-running timing jitter of ≈400 fs which is an upper limit because the measurement was already system noise limited above 10 kHz.
