Abstract

In this paper we describe a method which was used to lock the pulse repetition frequency and phase of one (passively modelocked) laser to that of another so that the pulses from both lasers were maintained in temporal synchronism. Both lasers retained their independence in all respects so that different wavelengths and pulse durations could be selected as required. Such a system would provide a relatively cheap, simple and versatile tool for applications requiring dual wavelength pump-probe measurements.
