Laboratory experimentation used a wide range of input parameters that when combined produced brilliant sparks in air. The results show a strong dependence of the output on the output coupler reflectivity, Q-switch initial transmission, and gain media dopant concentration. The results show peak power levels of up to 3MW and peak focal intensities of up to 560 GW\/cm2. Engine testing was performed on a Ricardo Proteus single cylinder research engine. The engine testing consisted of a comparison of the in-cylinder, and emissions behavior. All engine parameters were kept as constant and the equivalence ratio was varied between 0.8, 0.9, and 1.0. The test laser was constructed with a 30% output coupler, 32% Q-switch initial transmission, and a 0.5% Nd concentration rod all pumped by approximately 1000 Watts of optical power. The test laser single mode output pulse had an energy of 23 mJ, with a pulsewidth of 10 ns, and an M2 value of 6.55. This output produced focal intensity of 270 GW\/cm2\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Dustin McIntyre\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3639113624\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783639113624\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e VDM Verlag\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 12\/29\/2008\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 224\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.67lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.47d","brand":"Dustin McIntyre","offers":[{"title":"Paperback","offer_id":44126001463551,"sku":"9783639113624","price":85.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_2aefb6c1-a8a6-4668-97bf-2a64579bc661.jpg?v=1687445738","url":"https:\/\/www.whiterainbookhouse.com\/products\/laser-spark-plug-development-and-dustin-mcintyre-9783639113624","provider":"WR Book House","version":"1.0","type":"link"}
