　　MaxLight product advantages

● Flat field grazing incidence spectrometer

● Exclusive slit free design

● Extremely high diffraction efficiency grating

The wavelength range is from 1 to 200nm

● Built in spot image analysis function

● Compact and modular design

Thanks to its slit free design, maxLIGHT provides extremely high light collection efficiency and high luminous flux in the industry. The aberration corrected flat field wavelength covers a range of 1nm to 200nm, with a wide spectral bandwidth, such as 5-80nm per grating. Modular design matches various experimental environments and configurations. MaxLIGHT has an integrated slit bracket and filter insertion unit, as well as an electric grating locator.

　　Flexible and comprehensive detector options:

XUV CCD camera for high resolution and high dynamic range

MCP/CMOS detector for widest wavelength coverage, gating, and enhanced detection.

　　No slit design

HPS's proprietary spectrometer design uses direct imaging technology with a light source. Therefore, there is no need for narrow entrance slits and the incident light can be collected to the maximum extent possible. Compared with traditional spectrometer architectures, the light intensity reaching the detector is 20 times higher, and this structure greatly improves the stability of daily operations.

　　measurement result

In the application of fitting spectra using attosecond XUV pulses, HHG was characterized by maxLIGHT XUV (left image). High order harmonics originate from single photon transitions (blue arrows), while two-photon transitions of XUV and IR light appear as sidebands in the photoelectron spectrum (right figure).

The HHG spectrum measured by maxLIGHT XUV (right figure) and the broadened spectrum of a 25fs fundamental frequency light pulse in a Kagom é photonic crystal fiber (left figure). As the pump energy increases, the effect of soliton blue shift on HHG is clearly visible.

At the same signal strength, the resolution of the maxLIGHT pro spectrometer (solid line) is significantly higher compared to the standard spectrometer (dashed line). To achieve equivalent spectral resolution, traditional spectrometer techniques require the setting of narrow slits, which significantly reduce signal intensity.

HHG spectra obtained using maxLIGHT XUV in the cutoff region at a repetition rate of 150kHz. The change in CEP shows that intensity modulation begins to disappear under certain CEP settings, indicating the presence of independent attosecond pulses.

The reference spectrum example demonstrates the resolution capability of the maxLIGHT spectrometer. As shown in the figure, the high-order harmonic spectrum after the interaction between femtosecond laser pulses and solid targets is filtered by a filter. The inherent fine structure spectrum in the harmonic generation process can be clearly distinguished by the maxLIGHT spectrometer.
