“…Femtosecond OPOs are typically synchronous with their pump laser, with the cavity length of the former matched to the latter. In harmonic pumping the OPO cavity length is chosen to be an integer [56,57] or integer fraction [58,59] of the pump cavity length, allowing high repetition rate pulse trains to be generated without the need for high repetition rate oscillator. Balskus et al used a 333 MHz Ti:sapphire laser to pump an OPO constructed in a fundamental (333 MHz) and harmonic (1 GHz) configuration, locking the CEO frequency of the signal in both cases, and compared the locking stability.…”

Techniques to measure and manipulate the carrier-envelope phase within femtosecond optical parametric oscillators (OPOs) allow their outputs to be stabilized in a way that produces a frequency comb structure, potentially tunable throughout the transparency band of the gain material. In this review we describe the fundamental principles of phase control, on which the development of singly-and doubly-resonant OPO frequency combs is based. We give examples of practical embodiments of such combs, and discuss in detail several applications, including spectroscopy, metrology, quantum computation and astrophotonics.

“…In this Letter we advance this concept by reducing the complexity of the seeding unit further by employing a harmonic cavity OPO (HC OPO) with just a fraction of the resonator length compared to the pump laser [25,26] as a seeding unit. This results in an exponentially decaying intra-cavity signal, where every nth (here: 10 th ) pulse serves as seed for the next frequency conversion process.…”

Compact harmonic cavity optical parametric oscillator for optical parametric amplifier seeding

We present a broadly tunable highly efficient frequency conversion scheme, based on a low-threshold harmonic cavity optical parametric oscillator (OPO) followed by an idler-seeded power amplifier. By choosing the cavity length of the OPO equal to the 10 th harmonic of its 41 MHz Yb:KGW solid-state pump laser, a very compact optical setup is achieved. A singly-resonant cavity without output coupler results in a low oscillation threshold of only 28-100 mW in the entire signal tuning range of 1.37-1.8 µm. The 2.4-4.15 µm idler radiation is coupled out at the 41 MHz pump frequency and employed to seed a post amplifier with nearly Watt-level output power. In addition, the seeder plus power amplifier concept results in clean signal and idler pulses at the fundamental repetition rate of 41 MHz with a time-bandwidth product below 0.4 and a relative intensity noise 10 dB lower compared to the solid-state pump laser.

“…One technique for reducing the size of an OPO is to change the OPO cavity length to a fractional length of the typical requirement for synchronous pumping [11,12]. This technique simultaneously changes the repetition rate of the OPO output at the cost of higher thresholds and additional amplitude fluctuations, which may be undesirable.…”
