“…An actively mode-locked Nd:YAG laser was therefore acquired and with it the benefits in reduced threshold energy for the shorter pulses were amply confirmed [13]. The frequency-doubled output of this laser was then used to synchronously pump a dye laser [14] which, in turn, provided a tunable pump with sufficient power to drive the stimulated Raman process. Having reached this point, with the capability to generate tunable infrared radiation it was already apparent that there was a better and simpler way to do this; simply cut out the dye-laser and the Raman medium, and replace these with an OPO, although this time in the form of a synchronously-pumped OPO (SPOPO), and making use of the new nonlinear materials that had recently emerged, such as BBO and KTP.…”

My first sight of a laser beam was in the Spring of 1963, during a year spent, as a graduate trainee, at the Great Baddow Research Labs of the Marconi Company. Midway through that year I was very fortunate to be offered participation in a project to construct a He-Ne laser. Having graduated the year before, with a mathematics degree from Cambridge University, I was acutely conscious of my limited knowledge of experimental physics, particularly when it came to dealing with RF power supplies, vacuum systems and the like. In my inexperienced hands the whole of this 'home-made' laser seemed to consist of hazardous and lifethreatening unknowns. So, when, as a result of my ministrations, it first sprang into life and lased before my eyes, no-one could have been more delighted and surprised than I. This intensely rewarding experience formed a number of attitudes that have endured over the ensuing 38 years.
