Fisikawan ciptakan model terpadu untuk denyut laser yang berirama

Sebuah tim peneliti internasional telah mengembangkan kerangka kerja matematis tunggal yang menjelaskan perilaku ritmik tidak biasa dari denyut laser berirama (breather laser pulses). Terobosan ini menyatukan dua rezim dinamika laser yang sebelumnya terpisah untuk pertama kalinya.

Para peneliti, termasuk Dr. Sonia Boscolo dari Aston University, mempublikasikan temuan mereka di Physical Review Letters. Studi tersebut menunjukkan bahwa siklus irama cepat maupun lambat pada laser ultra-cepat muncul dari proses fisik yang berkaitan, bukan dari mekanisme yang berbeda. Breather di atas ambang batas (above-threshold) berosilasi dengan cepat dan terkunci pada rongga laser, sementara breather di bawah ambang batas (below-threshold) berevolusi secara perlahan melalui kombinasi Q-switching dan pembentukan soliton.

Researchers at East China Normal University have developed a new imaging technique that captures ultrafast events in trillionths of a second, revealing both brightness and structural changes in a single shot. The method, called compressed spectral-temporal coherent modulation femtosecond imaging (CST-CMFI), tracks phenomena like plasma formation and electron movement. Yunhua Yao, the team leader, described it as a major advance for physics, chemistry, and materials science.

An international team of physicists has found that quantum collapse models, potentially linked to gravity, introduce a minuscule uncertainty in time itself. This sets a fundamental limit on clock precision, though far below current detection levels. The research, published in Physical Review Research, explores ties between quantum mechanics and gravity.
