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\u003c\/p\u003e\u003cdiv\u003e\n\u003cstrong\u003eNumber of Pages:\u003c\/strong\u003e 224\u003c\/div\u003e\u003cdiv\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.47 x 9 x 6 IN\u003c\/div\u003e\u003cdiv\u003e\n\u003cstrong\u003ePublication Date:\u003c\/strong\u003e December 29, 2008\u003c\/div\u003e","brand":"Books by splitShops","offers":[{"title":"Default Title","offer_id":42165007351943,"sku":"9783639113624","price":122.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/2623\/2711\/files\/04ad96f0cb8e8f5151d21dd493b1ef3a.webp?v=1733310236","url":"https:\/\/booksby.splitshops.com\/products\/laser-spark-plug-development-and-engine-testing-design-of-a-diode-side-pumped-solid-state-passively-q-switched-laser-for-use-as-an-ignition-source-f-paperback","provider":"Books by splitShops","version":"1.0","type":"link"}
