The development of fiber laser systems in the last 60 years

In the last 60 years, fiber laser systems have reached great successes, herewith, almost all features have resulted in a very high level. Now fiber lasers find their applications in numerous areas such as materials science, bio-imaging, communications, energy sciences, industrial processing, fundamental physics, etc.

Today researchers study the most critical and potentially productive questions in fiber laser technology that include the growth in power (peak power and average power as well) that greatly moves forward and opens new applications of laser systems. Additionally, compact and portable space-based laser technology is accessible in various applications.

For instance, researchers from China have launched the station of extreme light projects, the large ultra-intense fiber laser being built in China. Nowadays “most of the engineering designs have been finished, and the front end of the facility, which can be regarded as a small prototype of the laser system facility, is being developed.” This project includes a 100-PW fiber laser system that will be created, which can offer a focused intensity of more than 1023 W/cm2.

Moreover, this fiber laser is able to operate with a hard X-ray for pump-probe tests, for example, experimentally verifying the vacuum birefringence phenomenon. The laser technology is based on optical parametric chirped-pulse amplification as a crucial advantageous technology that plays a highly important role. The thing is that compared to standard Ti: sapphire, the new laser system offers broader bandwidth, higher single-pass gain, and less thermal effect, which provides higher-energy amplification with shorter compressed laser beam pulse durations.

Herewith, the 100-PW  fiber laser system has a higher single-pass gain and related shorter optical distance that is advantageous for coherent laser beam combination and micrometer precision levels. The fiber laser technology provides an application of strong fields offered by laser beams to break down and explore the quantum vacuum. 

It should be noted that vacuum QED is considered to be one of the most promising applications for the fiber laser facility, and the collision of the 100-PW laser system and XFEL laser beams to examine the vacuum birefringence effect is regarded as the “day-one” experiment. Also, the creation of high-energy particles and radiation can become another very interesting application.
