Abstract

We propose a scheme for optimizing the time delay between the pump and seed pulses of an optical parametric amplifier (OPA) over a large spectral range. The efficiency of this method is demonstrated for a femtosecond BBO parametric amplifier seeded with a white-light continuum pulse. The error signal used for intensity stabilization results from a modulation of the temporal delay between the pump and the continuum pulses and phase-sensitive detection of the amplified signal. It allows us to lock the delay to the position that maximizes the OPA gain.

Experimental setup: B.S., beam splitter; D.M., dichroic mirror; S.M., stepping motor; WLC, white-light continuum. Mirror M1 is mounted on a PZT. The two lenses, f 1 and f 2, allow for a beam cross-sectional reduction by a factor of 5.

(a) Measure of the frequency chirp of our water-generated continuum. The continuous curve is just a guide for the eyes. (b) Curves (1)–(6) represent the temporal evolution of amplified pulse spectra when the stabilization is turned on, after the OPA crystal has been tilted for wavelength change. Each spectrum was recorded after stabilization was turned on for approximately 2 s and then turned off.

Fig. 3
Fig. 3

Error signal measured as a function of the delay line position when a sinusoidal voltage (inset curve I) is applied to the PZT of mirror M1. The inset shows the experimental output of our OPA for two different positions, denoted as B and C in the main diagram, that correspond to the intensity modulations presented in the inset curves B and C. As expected, the signal recorded by the photodiode is either in or out of phase when the sinusoidal voltage is applied.
