Laser ZEUS dispara 2 petawatts nos EUA e abre caminho para avanços em medicina, física e astrofísica, com previsão de experimentos inéditos
(Imagem: Marcin Szczepanski / Michigan Engineering) O laser mais poderoso dos Estados Unidos acaba de ser testado com sucesso. Chamado de ZEUS — sigla para Zettawatt-Equivalent Ultrashort pulse laser System —, o equipamento alcançou 2 petawatts de potência em sua primeira demonstração oficial. O número impressiona: são 2 quatrilhões de watts , mais de cem vezes a produção total de eletricidade do planeta. Ainda assim, a emissão durou tão pouco que seria imperceptível a olho nu.
A novidade foi anunciada pela Universidade de Michigan , responsável pelo projeto. ZEUS ocupa uma área semelhante à de uma academia esportiva e é considerado o sucessor direto do sistema HERCULES, que atingia até 300 terawatts. A construção do novo laser custou US$ 16 milhões e foi descrita pela instituição como uma solução de alto desempenho a um custo reduzido, se comparado a outros sistemas de aceleração de partículas.
Primeiro teste usou hélio para gerar plasma e acelerar elétrons 466p1m Na demonstração inicial, ZEUS utilizou um alvo de hélio para produzir plasma. Um pulso de laser foi disparado contra uma célula contendo o gás, arrancando elétrons dos átomos e criando uma mistura de íons positivos e elétrons livres. Os elétrons então aram a ganhar velocidade logo atrás do pulso de luz em um processo chamado aceleração por campo de esteira (wakefield acceleration) . Esse fenômeno é possível porque a luz viaja mais devagar no plasma, permitindo que os elétrons se aproximem e aproveitem o pulso para ganhar ainda mais energia. O tamanho da câmara de testes também favorece esse ganho, permitindo que os elétrons atinjam velocidades mais altas do que em sistemas anteriores.

O experimento principal do ZEUS está previsto para ocorrer ainda em 2025 , e envolverá uma colisão entre os elétrons acelerados e pulsos de laser vindos da direção oposta. Esse tipo de interação cria um efeito no qual um laser de 3 petawatts pode parecer até um milhão de vezes mais potente , justificando o termo “equivalente a zettawatt” no nome do sistema.
Para garantir a segurança durante os testes, ZEUS utiliza grades de difração óptica , que alongam o pulso inicial de infravermelho ao longo do tempo. A medida evita que o feixe atinja uma intensidade tão alta que possa causar a ionização do próprio ar ao seu redor.

A pesquisa é liderada pela Divisão de Física da National Science Foundation (NSF), nos Estados Unidos.
O equipamento também poderá ser usado para investigar fenômenos extremos do universo, como jatos de pósitrons emitidos por buracos negros e as causas de explosões de raios gama. Segundo o físico Franklin Dollar, da Universidade da Califórnia, um dos responsáveis pela experiência, “o ZEUS não é apenas um grande martelo de laser — a luz pode ser dividida em múltiplos feixes, o que amplia as possibilidades experimentais”.
