The present work study the optical parameters for CW operation in Ti:Sapphire laser system with the focus on stability zone and threshold pump power. The main aim of this study is to explore the influence of a broadband dielectric resonator mirrors used in the laser cavity on the stability zone and threshold pump power. This effect has been determined by using two types of mirrors with different broadband reflection. The experimental results show the dependence of the stability and laser threshold pump on broadband dielectric mirrors. For a broader dielectric mirror, the stability zone shows larger stable distance with respect to the narrower mirror. Moreover, the threshold pump for the broader band is smaller than the narrower. This study allows researcher choosing the appropriate optical components for generating more stable laser with small threshold pump power.

The wide application of laser systems and the increase in the values of their energy characteristics, which may hazard to the health of staff and other people in the area of direct and reflected laser radia­tion, necessitates a permanent dosimetric monito­ring in these areas. However, the methods of mea­suring the parameters of laser radiation at a given point in space to determine the degree of radiation safety for the human body, established in the stan­dard DSTU EN 60825-1: 2016, are difficult to implement when using obsolete monitoring equipment. Therefore, the development of an automated method for determining the characteristics of a laser system and the rapid detection and determination of the direction and coordinates of laser radiation is relevant. The proposed method for automated determination of the laser system characteristics differs by applying an additional measurement channel with a photodetector, as in the main channel, and a compensated filter to ensure the difference of the rea­dings in the channels, so that each difference of measured channel values corresponds to the one wavelength value. For the formation of a compensation filter with a constant spectral characteristic in the most demanded wavelength range from 0.4 microns to 1.1 microns are used by known methods of calculation and manufacturing. A combination of optical glass NSNU 13 and SZS-9 with varying thickness as a compensation filter is permitting measure of laser irradia­tion doze for radiation in this range with an error that does not exceed 15%. It is necessary to perform the tasks of quickly finding and estimating the angular coordinates of the laser sources for monitoring the parameters of laser radiation in the working area. Improving the design of the device for detecting and determining the angular coordinates of laser radiation is made by using an optical system that directs laser radiation to a photodetector of radiation and an information processing unit, in front of which a volume matted screen is installed so that the distance from the middle of the optical system to the nearest point of the screen is greater distance of the optical system. The photodetector matrix installed in the optical system focus is used as a photodetector of laser radiation. The application of spherical screens for direct laser radiation and cones for diffused and diffused reflec­ted radiation is proposed for the effective and rapid determination of radiation corners in the working zone. Dosimeters with automated wavelength monitoring and detection and determination of the angular coordinates of laser radiation will facilitate and reduce the cost of conducting dosimetry monitoring.

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.
