Then Dr. Chu showed us how to adjust the M1 mirror tilt, P1 focus, and M3 focus while optimizing the cavity at each adjustment! We ended up with 960 mW for bare cavity alignment! While cleaning all the mirrors Dr. Chu cleaned the bottom side of a compensation rhomb, talking about her experience how that usually ends up giving more power as the dye vapors (probably) deposit on the bottom side of the rhomb. As she said this and cleaned the rhomb we immediately saw a ~50mW increase in power, putting us at just above 1.01 W! On optimizing the cavity further we were able to get 1.03 W out of the bare cavity alignment! <\/p>\n\n\n\n<p>Safe to say this week our happiness index correlated with our RDL power! <\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:100%\">\n<figure class=\"wp-block-gallery aligncenter columns-2 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\"><ul class=\"blocks-gallery-grid\"><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"1014\" height=\"1024\" src=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2021\/09\/IMG_5939-1014x1024.jpg\" alt=\"\" data-id=\"297\" data-link=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/?attachment_id=297#main\" class=\"wp-image-297\" srcset=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2021\/09\/IMG_5939-1014x1024.jpg 1014w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2021\/09\/IMG_5939-297x300.jpg 297w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2021\/09\/IMG_5939-150x150.jpg 150w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2021\/09\/IMG_5939-768x776.jpg 768w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2021\/09\/IMG_5939.jpg 1020w\" sizes=\"auto, (max-width: 1014px) 100vw, 1014px\" \/><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"875\" height=\"1024\" src=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2021\/09\/IMG_5946-copy-875x1024.png\" alt=\"\" data-id=\"302\" data-full-url=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2021\/09\/IMG_5946-copy.png\" data-link=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/?attachment_id=302#main\" class=\"wp-image-302\" srcset=\"https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2021\/09\/IMG_5946-copy-875x1024.png 875w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2021\/09\/IMG_5946-copy-256x300.png 256w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2021\/09\/IMG_5946-copy-768x899.png 768w, https:\/\/ciresblogs.colorado.edu\/lidarexploration\/wp-content\/uploads\/sites\/73\/2021\/09\/IMG_5946-copy.png 1170w\" sizes=\"auto, (max-width: 875px) 100vw, 875px\" \/><\/figure><\/li><\/ul><figcaption class=\"blocks-gallery-caption\">Working on the RDL!<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n<figure class=\"wp-block-pullquote\" style=\"border-color:#000000\"><blockquote class=\"has-text-color\" style=\"color:#0ea032\"><p>This week India (5th September) and China (10th September) celebrated Teacher&#8217;s Day! <\/p><p>Cheers to Dr. Chu for being an amazing teacher! <\/p><p>Happy Teacher&#8217;s Day to teachers worldwide!<\/p><\/blockquote><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>This week we opened up the RDL to understand its anatomy and got much more power out!
