“…In this relation, we would like to draw attention to the possibility of creating an adjustable feedback in the external cavity with volume holographic grating (VGH). In recent years, the external cavity with VGH have attracted considerable attention both for creation of high-monochromatic lasers with high stability of the radiation wavelength [2][3][4], and, importantly, for work in external cavities of laser-array bars with high output power of radiation [5,6].…”

To achieve the maximum efficiency in single-frequency lasing mode of laser diode with external cavity, it is necessary to minimize losses in the optical system for the output beam and to provide the optimal frequency-selective feedback. In this paper, we have investigated the scheme of an external cavity diode laser (ECDL) based on phase volume holographic grating (VHG). Angular and spectral selectivities of the holographic grating allow to adjust the optical feedback with low losses in the cavity, and it can be used for the frequency narrowing of diode-array bars. Here, the optimal parameters of VHG and the temperature dependence of the diode laser bar spectrum have been studied, and the proposals on VHG design have been developed.
