Ruby laser rods are chromium-doped sapphire, also written Cr:Al₂O₃, and were used as solid-state laser gain media in pulsed ruby laser and early optical maser systems. The pink coloration is consistent with chromium-doped synthetic sapphire \/ laser ruby material, though exact dopant concentration, coatings, orientation, transmission, and lasing performance have not been tested. Meller Optics has a long history in precision sapphire and ruby optics, including early ruby laser rod fabrication for MIT\/NASA lunar ranging work. Useful for solid-state laser restoration, optics collecting, lab display, research parts, or vintage laser system spares. Sold as a vintage optical crystal only; inspect photos for end condition, coating condition, chips, markings, and included holders.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cp dir=\"ltr\" style=\"margin-top:0; margin-bottom:0;\"\u003eLM\u003c\/p\u003e","brand":"Lab Liquidators Store","offers":[{"title":"Default Title","offer_id":55356989210916,"sku":"SP111115266","price":359.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/5289\/2964\/files\/10_aab5bf8e-3137-4676-8d5e-c3f0af0ee473.jpg?v=1782484877","url":"https:\/\/store.labliquidators.com\/products\/adolf-meller-optics-ruby-laser-rod-52mm-x-6mm-pink-sapphire-maser-crystal","provider":"Lab Liquidators Store","version":"1.0","type":"link"}
