“…The primary pump source for our OPCPA system is an industrial laser (Time-Bandwidth-Products Inc., Duetto) operating at 1.064 μm and delivering 12 ps pulses at a repetition rate of 50 kHz and average output power of up to 10 W. The output of this laser is split in two parts. One part is further amplified by a Nd:YVO 4 Innoslab-type amplifier [26], to provide a higher-power pump for the final OPA stage. The remaining part is collinearly overlapped with the seed in OPA1 via a dichroic mirror, denoted DM1 in Fig.…”

We generate sub-four-cycle pulses (41.6 fs) with 12 μJ of pulse energy in the mid-infrared spectral range (center wavelength 3.4 μm) from a high-repetition-rate, collinear three-stage optical parametric chirped-pulse amplifier (OPCPA) operating at 50 kHz. Apodized aperiodically poled MgO:LiNbO3 crystals with a negative chirp rate are employed as gain media to achieve ultrabroadband phase-matching while minimizing optical parametric generation. The seed pulses are obtained via a 1.56 μm femtosecond fiber laser, which is spectrally broadened in a dispersion-shifted telecom fiber to support 1000 nm bandwidth idler pulses in the mid-infrared.

“…For completeness, we next give an overview of the system layout. The OPCPA system is pumped at 1064-nm by an industrial laser (Time Bandwidth Products "Duetto") which produces 12-ps pulses at a repetition rate of 50 kHz and average power of 10 W. Approximately 6 W from this laser is used for pumping our APPLN-based pre-amplifiers, while the remaining power is used to seed a home-built Innoslab amplifier [22], which currently provides up to 17.8 W when operated at 50 kHz. To seed the OPCPA system, we use a femtosecond fiber laser which produces 65-fs pulses at 82-MHz at a center wavelength of 1560 nm.…”

Abstract:We demonstrate a new regime for mid-infrared optical parametric chirped pulse amplification (OPCPA) based on achromatic quasi-phase-matching. Our midinfrared OPCPA system is based on collinear aperiodically poled lithium niobate (APPLN) pre-amplifiers and a non-collinear PPLN power amplifier. The idler output has a bandwidth of 800 nm centered at 3.4 µm. After compression, we obtain a pulse duration of 44.2 fs and a pulse energy of 21.8 µJ at a repetition rate of 50 kHz. We explain the wide applicability of the non-collinear QPM amplification scheme we used, including how it can enable octave-spanning OPCPA in a single device when combined with an aperiodic QPM grating.

“…103 Another system has been demonstrated based on Nd∶YVO 4 slab amplifier with 0.6 mJ pulse energy and 12 ps duration corresponding to an average/peak power between 46 W∕38 MW and 30 W∕50 MW. 95 All of these systems offer high performance with compact footprint due to the MOPA architecture. Compared to Nd-based amplifiers, the quantum defect is ∼10% in Yb:YAG whereas it is ∼25% in Nd:YAG, resulting in higher optical-to-optical efficiency and lower thermal load at comparable operational power.…”

Abstract. More than 20 years after the first presentation of optical parametric chirped-pulse amplification (OPCPA), the technology has matured as a powerful technique to produce high-intensity, few-cycle, and ultrashort laser pulses. The output characteristics of these systems cover a wide range of center wavelengths, pulse energies, and average powers. The current record performance of table-top, few-cycle OPCPA systems are 16 TW peak power and 22 W average power, which show that OPCPA is able to directly compete with Ti:sapphire chirped-pulse amplification-based systems as source for intense optical pulses. Here, we review the concepts of OPCPA and present the current state-of-the art performance level for several systems reported in the literature. To date, the performance of these systems is most generally limited by the employed pump laser. Thus, we present a comprehensive review on the recent progress in high-energy, high-average-power, picosecond laser systems, which provide improved performance relative to OPCPA pump lasers employed to date. From here, the impact of these novel pump lasers on table-top, few-cycle OPCPA is detailed and the prospects for next-generation OPCPA systems are discussed.
