Laser amplification energy storage

Can laser irradiation regulate energy storage and conversion materials?

Here, the recent efforts on regulating energy storage and conversion materials using laser irradiation are comprehensively summarized. The uniqueness of laser irradiation, such as rapid heating and cooling, excellent controllability, and low thermal budget, is highlighted to shed some light on the further development of this emerging field.

How can a large-area processable light source improve optical energy density?

To address this issue, large-area processable light sources (e.g., line beam lasers, and flash lamps) along with optical beam shaping technologies can be introduced to enable required optical energy density over broad surfaces without sacrificing process quality and precision.

How much power does a slab amplifier produce?

By capitalizing on the high energy storage capability inherent in the slab amplifier, the laser system achieves a remarkable output of high-power laser amplification. In this work, 1240 W of average power is obtained, corresponding to the single-pulse energy of 62 mJ at the pulse width of 300 ns.

What are the recent advances of Lig in energy materials?

In this review, we highlight the recent advances of LIG in energy materials, covering the fabrication methods, performance enhancement strategies, and device integration of LIG-based electrodes and devices in the area of hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction, zinc-air batteries, and supercapacitors.

Which materials can be modulated using lasers?

Up to now, a vast spectrum of materials including carbons, metal oxides, and metal carbides have been precisely modulated at atomic-, nano-, and/or macroscales into the desired structures using different types of lasers (Table 1), with fundamentally improved capability for energy storage and conversion.

How does a drive laser work?

The drive laser provides 2.2-J, 35-fs (full width at half maximum (FWHM)) pulses on target at 1-Hz repetition rate. Through the interaction with a 5-mm-long plasma source, the set-up provides electron beams with an energy of 257 megaelectronvolts (MeV) at 41 pC (13 pC rms) of charge and a typical energy spread of 1.8% and energy jitter of 3.5%.
