The study explored the process of rearrangement of the Earth ’s core at the atomic level under high temperature and high pressure. The thermodynamic properties of these high-pressure states affect the Earth ’s magnetic field, thereby protecting us from the solar wind and enabling us to survive on Earth. This laser upgrade will allow for higher pressure and temperature conditions in her samples, which is also a long-term goal.
High strength + precision. The optical laser pointer amplifies the low-power beam in stages and reaches higher and higher energies. However, the quality of the laser beam and the ability to control the laser beam gradually decrease during beam amplification. Low-quality pulses may eventually form a completely different shape, which is useless for researchers trying to recreate specific conditions.
The MEC laser area manager stated: “The initial low-energy pulse must have the original spatial pattern and the correct configuration of the time shape-that is, the pulse power is accurately shaped before amplification, which changes over time and is then generated for each user’s experiment. Required laser pulse characteristics. ”
Each target is unique and requires a specific green laser pointer energy and pulse shape, which makes manual testing and adjustment time-consuming. Prior to the upgrade, the team manually optimized the pulse shape and spent hours, or even days, performing proper calibration. To solve this problem, laser scientists have developed an automated control system for adjusting low-power beams before amplification.
The new system allows precise customization of pulse shape using a computerized feedback loop system to analyze the pulse and automatically recalibrate the laser. “The new optimizer is a system that can generate many high-quality pulses in the most accurate and timely manner.
In addition to the improved pulse shape, the upgraded system can consistently store the energy on the sample, which allows researchers to reproduce the extreme material state in their samples very carefully. As a result, data quality and operational efficiency have been improved. Human strength and technology have contributed to the success of the instrument: “The capabilities and qualifications of laser scientists and engineers at the MEC experimental station provide researchers with the technical resources needed to explore unsolved cosmic problems and realize their theory.
