The sensitivity of these laser interferometers is so incredible that the quantum effects of the employed light have already become limiting. Ultra-precisely stabilised lasers do not suffice; non-classical light is already routinely employed in the current (second) generation GWDs (such as Advanced LIGO and Advanced Virgo). Other noise sources, such as seismic and thermal noise, pose further challenges for next-generation detectors.<\/p>\n\n\n\n<p>To achieve ever-higher detection rates for meaningful gravitational wave astronomy, ever-greater detection sensitivity is required. In this talk, I will introduce the principle of interferometric gravitational wave detection, briefly describe the current status of the field, and highlight some of the advanced technologies employed in current GWDs. I will end with an outlook on the next (third) generation of GWDs, such as the planned European gravitational wave observatory, the Einstein Telescope.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Video<\/h1>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-4-3 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" class=\"youtube-player\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/VMk5KTLzE6U?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=en-US&#038;autohide=2&#038;wmode=transparent\" allowfullscreen=\"true\" style=\"border:0;\" sandbox=\"allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox\"><\/iframe><\/span>\n<\/div><\/figure>\n\n\n\n<h1 class=\"wp-block-heading\">Presentation<\/h1>\n\n\n\n<div data-wp-interactive=\"core\/file\" class=\"wp-block-file alignwide\"><object data-wp-bind--hidden=\"!state.hasPdfPreview\" hidden class=\"wp-block-file__embed\" data=\"https:\/\/www.matterwaveoptics.eu\/FOMO2024\/wp-content\/uploads\/2024\/07\/Michele-Heurs-The-past-present-and-future-of-ground-based-laser-interferometric-gravitational-wave-detection.pdf\" type=\"application\/pdf\" style=\"width:100%;height:670px\" aria-label=\"Embed of Mich\u00e8le Heurs -- The past, present, and future of (ground-based) laser-interferometric gravitational wave detection.\"><\/object><a id=\"wp-block-file--media-c2f17474-441b-40e6-a158-21d90796ec76\" href=\"https:\/\/www.matterwaveoptics.eu\/FOMO2024\/wp-content\/uploads\/2024\/07\/Michele-Heurs-The-past-present-and-future-of-ground-based-laser-interferometric-gravitational-wave-detection.pdf\">Mich\u00e8le Heurs &#8212; The past, present, and future of (ground-based) laser-interferometric gravitational wave detection<\/a><a href=\"https:\/\/www.matterwaveoptics.eu\/FOMO2024\/wp-content\/uploads\/2024\/07\/Michele-Heurs-The-past-present-and-future-of-ground-based-laser-interferometric-gravitational-wave-detection.pdf\" class=\"wp-block-file__button wp-element-button\" download aria-describedby=\"wp-block-file--media-c2f17474-441b-40e6-a158-21d90796ec76\">Download<\/a><\/div>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"373\" height=\"89\" data-attachment-id=\"1104\" data-permalink=\"https:\/\/www.matterwaveoptics.eu\/FOMO2024\/michele-heurs\/ligo\/\" data-orig-file=\"https:\/\/www.matterwaveoptics.eu\/FOMO2024\/wp-content\/uploads\/2024\/07\/ligo.gif\" data-orig-size=\"373,89\" data-comments-opened=\"0\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"ligo\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/www.matterwaveoptics.eu\/FOMO2024\/wp-content\/uploads\/2024\/07\/ligo.gif\" src=\"https:\/\/www.matterwaveoptics.eu\/FOMO2024\/wp-content\/uploads\/2024\/07\/ligo.gif\" alt=\"\" class=\"wp-image-1104\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Mich\u00e8le Heurs Abstract Since the first direct detection of gravitational waves in 2015, we have gained an entirely new observation window to the universe \u2013 now, we not only have electromagnetic telescopes and neutrino detectors to view astrophysical events, but we can also&nbsp;listen&nbsp;to the cosmos using interferometric gravitational wave detectors (GWDs).
