Abstract

The invention belongs to the technical field of plant growth equipment, and relates to a red and blue laser plant lamp. A laser gain crystal is fixedly connected with a laser, and the laser pumps the laser gain crystal to generate laser oscillation; a frequency doubling crystal is arranged at one end of the laser gain crystal, and a frequency synthesis crystal is arranged at the other end of the laser gain crystal; a first laser cavity lens is arranged at an output end of the frequency doubling crystal, and a second laser cavity lens is arranged at an output end of the frequency synthesis crystal; a first beam expander is arranged at an output end of the first laser cavity lens; and a second beam expander is arranged at an output end of the second laser cavity lens. The red and blue laser plant lamp is simple in structure, large in illumination space and wide in range and can simultaneously output red laser and blue laser, the spectral range is wide, the output energy is large, the lamp is energy-saving and efficient, and the illumination range and the light power can be adjusted.

Description

Technical field: [0001] The invention belongs to the technical field of plant growth equipment, and relates to a red and blue plant lamp for promoting plant growth, in particular to a red and blue laser plant lamp. Background technique: [0002] Plants rely on the energy of sunlight for photosynthesis to grow, bloom, and bear fruit. The solar spectrum is a continuous spectrum, including all wavelengths from 400 to 760nm. Light of different wavelengths has different effects on plant photosynthesis, among which 400 to 520nm The blue light of 520-610nm and the red light of 610-720nm contribute the most to photosynthesis, and the ratio of green light of 520-610nm absorbed by plant pigments is very low. Studies have shown that the spectral energy distribution of red light and blue light is consistent with the absorption spectrum of chlorophyll. The combination of red and blue light can greatly promote the photosynthesis of plants and improve the growth and development of plants. ...
