Abstract

We demonstrate a mid-IR frequency comb centered at 3120 nm with 650-nm (20-THz) bandwidth at a comb-teeth spacing of 500 MHz. The generated comb is based on a compact ring-type synchronously pumped optical parametric oscillator (SPOPO) operating at degeneracy and pumped by a mode-locked Er-doped 1560 nm fiber laser at a repetition rate of 100 MHz. We achieve high-repetition rate by using a fractional-length cavity with a roundtrip length of 60 cm, which is one-fifth of the length dictated by conventional synchronous pumping.

Schematic of the fractional-length degenerate SPOPO. M2 and M3 are concave mirrors, and M1 and M4 are flat mirrors. The output coupler (OC) is a pellicle beamsplitter. An InAs photodetector (PD) is located after a Ge long pass filter (>2.5μm). The blue beam represents near-IR (1.56 μm). The red beam represents the mid-IR (3.12 μm). The green beam represents the overlap of the near-IR and mid-IR.

(a) Measured output spectrum as the cavity length is swept. The output of the SPOPO was measured through mirror, M1. The SPOPO oscillates at several discrete cavity lengths. (b) Oscillation peaks observed when a pellicle beamsplitter is used as an OC. The number of peaks is reduced to three and they are separated by 312 nm or λp/5.

(b) The SHG 1560 nm output of the SPOPO is shown. Significant residual pump is seen in the first pulse located at 1 ns. The inset shows a close up of pulses 2–5, which are not present when the SPOPO is not oscillating.

(a) Optical spectrum of the SPOPO output with 8.5 mW average power. The 3dB bandwidth is approximately 144 nm. Additionally the spectrum covers a 650 nm (20 THz) bandwidth at 35dB. (b) Measured interferometric autocorrelation of the 500 MHz pulse train with 8.5-mW average power. The trace suggests the pulse length at the output of the SPOPO is 109 fs.
