Ultrafast fiber laser for special materials research

Through the new applications and the traditional laser market share comparison, the fiber laser market to further enhance it is possible. Researchers are also applying ultra-fast fiber laser technology to multi-user applications such as the National Accelerator Laboratory in Stanford and the Lawrence Berkeley National Laboratory in Berkeley All in California. The development of synchrotrons and free-electron lasers (FELs) has given researchers access to brighter, shorter X-ray sources. For years, Stanford Synchrotron Light Sources (SSRL) provided X-ray pulses to study the molecular and crystalline structure of materials. Recently, a "low-alpha mode" of research and development, X-ray pulses up to 1 ps. At the same time, the linear accelerator-dependent coherent light source (LCLS) at the Stanford Linear Accelerator Center (SLAC) provides hundreds of hundred femtosecond pulses at approximately 1012 X-ray photons at wavelengths as short as 0.15 nm. These ultra-fast, solid X-ray pulses, combined with their high spatial and temporal coherence, enable new scientific research from 3-D imaging and critical biomolecular dynamics to characterization of transient state studies. In synchrotrons and free-electron lasers (FELs), energy is transferred by a beam of electrons in a changing magnetic field. The electron travel route is affected by a magnet array of reversed polarity, bending back and forth, resulting in the release of energy in the form of light. In the case of synchrotron, the laser is spatially discontinuous with a typical pulse of 100 fs, but free electron lasers (FELs) emit intense, spatially coherent light beams with pulse widths as short as tens of femtoseconds. In order to work at a stable X-ray wavelength, the electron beams must be tightly bundled so that they are interdependent with the released light (effectively to achieve stimulated emission). Because the free-electron laser FEL has no resonator and is a single pass device, a very bright laser beam is required to reach the gain-saturation state. This is sometimes accomplished by using a conventional ultrafast laser source (such as Nd: YLF or Ti: sapphire) to excite the photocathode in the accelerated RF region and act as an electronic syringe. Lock to main clock by ultrafast laser to get synchronization signal. The master clock is controlling the linear accelerator. Figure 1.

However, a major drawback for each of these structures is that conventional solid state ultrafast amplifiers typically consume a large optical platform and require routine maintenance to ensure their best performance. Stanford University professor Aaron Lindenberg overcame this issue at Stanford's synchrotron laboratory using one-click ultrafast fiber lasers from Calmar's Cazadero range. Designed for use in OEM medical and microelectronic processing, the laser is compact, small, easy to set up, easy to set up and easy to adjust. In addition, its high pulse energy (up to 20uJ <500fs) and high repetition rate have taken advantage of Stanford Synchrotron Radiation Laboratory. A good time-resolved time-resolved study was achieved.
