Abstract

We present a technique that enhances the intensity of a nanosecond laser pulse by confining it in an enhancement cavity. The point of the technique is that a weak continuous-wave laser radiation, locked to the enhancement cavity, is injected into a nanosecond injection-locked pulsed laser as a seed. This leads to a stable confinement of the nanosecond pulse in the enhancement cavity. It is demonstrated that the pulsed intensity is enhanced by a factor of 120 for a 40-ns pulse, consistent with the theoretical prediction.

  8. We assume a typical specification of 7 mJ, 10 kHz at 532 nm for a high-repetition-rate, LD-pump, nanosecond pulsed laser. When we generate a tunable nanosecond single-frequency pulse with a specification of 2.5 mJ at 30 ns by employing such a nanosecond pulsed laser as a pump and then confine such pulses in an enhancement cavity with a finesse of 250, we can achieve a radiation intensity of 50 GW/cm2 and a Rayleigh length of 10 cm (beam waist diameter: ?200 ?m) at a repetition rate of 10 kHz.

  10. In Figure 4, the peak of the transmitted pulse was delayed by 18.6 ns against that of the incident pulse. This delay is equivalent to the slowing of the light velocity by a factor of 1/74 against the speed of light in vacuum, since the cavity length was 7.5 cm.
