“…This performance level is important for minimizing the Dick effect in optical clocks and enabling coherent interrogation of ultra-long-lifetime atomic states [20]. Yet increasing challenges of further reducing cavity thermal noise [21] have spurred research in alternative approaches aimed at circumventing the thermal noise problem, including superradiant lasers [22][23][24] and spectral hole burning [25].…”

We demonstrate Ramsey-Bordé (RB) atom interferometry for high performance laser stabilization with fractional frequency instability < 2 × 10 −16 for timescales between 10 and 1000s. The RB spectroscopy laser interrogates two counterpropagating 40 Ca beams on the 1 S0 -3 P1 transition at 657 nm, yielding 1.6 kHz linewidth interference fringes. Fluorescence detection of the excited state population is performed on the (4s4p) 3 P1 -(4p 2 ) 3 P0 transition at 431 nm. Minimal thermal shielding and no vibration isolation are used. These stability results surpass performance from other thermal atomic or molecular systems by one to two orders of magnitude, and further improvements look feasible. arXiv:1907.06774v1 [physics.atom-ph]

“…[3,4] So far, using narrow-linewidth solid-state lasers as fundamental frequency sources for frequency conversion, has been the most popular method to produce UV lasers. [5][6][7][8][9][10][11][12][13][14] In addition, narrow-linewidth fiber lasers are also potential fundamental frequency sources, which can provide better-quality beams, improved compactness, higher stability and efficiency. [15] Furthermore, narrow-linewidth fiber lasers are easy to achieve tunable repetition frequency and pulse width, compared with solid-state lasers.…”

We report on a compact, stable, all-fiberized narrow-linewidth (0.045 nm) pulsed laser source emitting laser beam with a wavelength of 266 nm, and tunable pulse width and repetition rate. The system is based on all-fiberized nanosecond amplifier architecture, which consists of Yb-doped fiber preamplifiers and a super-large-mode-area Yb-doped fiber power amplifier. The fiber amplifier with a core of 50 μm is used to raise the threshold of the stimulated Brillouin scattering (SBS) effect and to obtain high output power and single pulse energy. Using lithium triborate (LBO) crystal and beta-barium borate (BBO) crystal for realizing the second-harmonic generation (SHG) and fourth-harmonic generation (FHG), we achieve 17 μJ (1.73 W) and 0.66 μJ (66 mW), respectively, at wavelengths of 532 nm and 266 nm and a repetition rate of 100 kHz with pulse width of 4 ns. This source has great potential applications in fluorescence research and solar-blind ultraviolet optical communication.

“…It is impossible to fully remove As from arsenic iron ores because of the limited dearsenification ability of ironmaking process. 4,5) Although both slag treatment and vacuum treatment can partly remove As from arsenic molten iron in the steelmaking process, they also result in serious pollution or massive iron loss. Currently, a mainstream solution to this problem is diluting arsenic molten iron with arsenic-free molten iron in the steelmaking process.…”

An in situ Study of the Formation of Rare Earth Inclusions in Arsenic High Carbon Steels

et al. 2019

The application of rare earths is an effective way to stabilize residual elements in steel, such as As and P, so as to improve the performances of steel products. In situ methods were used to investigate the formation of inclusions and their stability at high temperatures in arsenic high carbon steels with additions of lanthanum. The results show that La 2 O 3 and La 2 O 2 S started generating in molten steel and had significant difference of appearances and growth behaviors. La 2 O 3 started with triangular particles and rapidly grew up like crystals; by contrast, La 2 O 2 S particles were always spherical or near-spherical and didn't significantly grow up. Arsenic existed as LaAsO 4 that turned out to be unstable under high temperatures. LaAsO 4 decomposed and As dissolved into the matrix when the temperature was higher than 1 200°C. The formation of LaAsO 4 during solidification and the dissolution of As into the matrix during heat treatment can effectively avoid the local enrichment of As. Therefore, it is possible to control As distributed uniformly in steel by appropriate heat treatment process.
