50 μJ, 90 ps Monolithic fiber amplifier passively Q-switched microchip laser with low timing jitter

Summary form only given. Diode-pumped passive Q-switched Nd: YVO4 microchip lasers are a simple low cost approach to generate optical pulses with high peak power and pulse durations below 100 ps [1] [2]. These lasers have a great potential for scientific and industrial applications. However the inherently large timing jitter of the interpulse period of the microchip laser may limit its applications, even if some relatively cumbersome techniques have been developed to reduce it [3]. Another limitation comes from high peak power which requires the use of large core microstructured fiber amplifiers to produce the required high energy. These fibers are not fully integrated because of the difficulty to splice them and unavailability of fiber components.
