“…Those lasers require precise alignment and are therefore sensitive to acoustic and mechanical disturbances, particularly when a spring-loaded kinematic mount is used to align the grating or feedback optics [13]. Another design uses a narrowband interference filter (IF) placed in a linear cavity as a frequency-selective component [14][15][16]. Because The wavelength of the transmission maximum depends on the angle of incidence, where the angle is the angle of incidence and the maximum wavelength is the transmitted wavelength at normal incidence, the wavelength can be tuned by turning the filter.…”

The National Time Service Center of China is developing a compact, highly stable, 698 nm external-cavity diode laser (ECDL) for dedicated use in a space strontium optical clock. This article presents the optical design, structural design, and preliminary performance of this ECDL. The ECDL uses a narrow-bandwidth interference filter for spectral selection and a cat’s-eye reflector for light feedback. To ensure long-term stable laser operation suitable for space applications, the connections among all the components are rigid and the design avoids any spring-loaded adjustment. The frequency of the first lateral rocking eigenmode is 2316 Hz. The ECDL operates near 698.45 nm, and it has a current-controlled tuning range over 40 GHz and a PZT-controlled tuning range of 3 GHz. The linewidth measured by the heterodyne beating between the ECDL and an ultra-stable laser with 1 Hz linewidth is about 180 kHz. At present, the ECDL has been applied to the principle prototype of the space ultra-stable laser system.

“…We could observe the possibility that RIMS can be presented by an alternatively designed ECDL, whose system is relatively simple and stable than a grating modulated ECDL system. We will evaluate a beam linewidth of the developed IF-ECDL system by optical beat signal [6,7] in the future, and then proceed the resonance ionization of strontium to evaluate the selectivity enhancement of the radioactive isotopes such as 90 Sr.…”

There are difficulties to analyze 90 Sr from the sample in the field due to less abundant (x10-9) than other strontium isotopes. Therefore, it requires developing the detecting system with high selectivity of isotopes. To present >10 7 selectivity of strontium isotopes detection, 689.44 nm (Γ= ~7.5 kHz; 5s 2 1 S 0-5s5p 3 P 1 o) is applied to do multi-step resonance ionization mass spectrometry. Here, we develop interference filtered external cavity diode laser system to enhance isotope selectivity of strontium with multi-step resonance ionization at 5s 2 1 S 0-5s5p 3 P 1 o-5s4d 3 D 2 .

“…In the laser system, an interference-filter-type ECDL (IF-ECDL) offers an ultra-narrow interference filter to replace the alignment-sensitive diffraction grating in the conventional Litman-Metcalf-type and Littrow-type [35,36]. It is easier to achieve the narrow linewidth and the sufficient stability of laser frequency, due to the insensitivity to the pressure, mechanical, thermal strain, etc.…”

We demonstrate the construction of the optical system in the atomic clock-beyond atomic fountain based on 87Rb atom. The optical system includes a high-stability laser system and an optical lattice. The high-stability laser system with the new scheme of frequency locking and shift is introduced in detail, which is an important laser source for laser cooling. The optimized frequency and intensity stability are achieved to 4 × 10–14τ−1/2 (τ is the averaging time) and 4 × 10–5τ−1/2, respectively, which are highly stable. On the basis of the conventional atomic fountain clock, the optical lattice is specially investigated along the direction of gravity and its characteristics are studied systematically. For the optimized and novel exploration, we predict the achievable stability of 3.6×10−14τ−1/2 and it has the potential to be improved to 3.6×10−15τ−1/2. The realizability of the construction due to the stabilized laser and optical lattice makes the beyond fountain promising candidate for the next-generation high performance microwave atomic clock.
