The picture shows an energy band diagram of a micro-resonator based on a GaAs semiconductor as studied in the experiment, in which a quantum condensation of light-matter coupled quasi-particles called exciton-polaritons (exciton-polaritons) - through two-photon absorption. The achievement paves the way for new coherent control schemes and the realization of an efficient laser source in the terahertz (THz) range of electromagnetic radiation

First observation of "two-photon absorption for quantum condensation"

The achievement may accelerate research in new quantum technologies and developments in security, biological sensing, wireless communication and more
Demonstrations of the new method (bottom row) that allows to get closer to the structure of the studied objects (top row) within 100 nanoseconds

Dr. Oren Raz came up with an idea for a new way to circumvent the phase reconstruction problem: to combine two ultra-fast laser flashes and measure them together, so that the combination between the two would act as a hologram

The shape of the flash - how to measure a very fast phenomenon using a much slower detector
