High Power Burst-Mode Laser Seeded by an Electro-Optic Q-Switched Hundreds Picosecond Oscillator

We have proposed and experimentally demonstrated a simple, compact hundreds picosecond (ps) burst-mode laser with good beam quality, seeded by a Q-switched microchip laser. The hundreds ps seed pulse was injected into a laser diode (LD) end-pumped electro-optic (EO) Q-switched Nd:YVO4 laser via a partial transmittance plan mirror. During a 20 kHz burst-mode operation, a hundreds ps burst-mode laser with a 19 ns envelope was obtained, delivering a burst energy of up to 0.49 mJ with a sub-pulse width of 741 ps and a sub-pulse interval of

$\sim \; 3.2$

ns. A good beam quality factor was measured to be

$M^{2}=1.19$

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
