The invention relates to a diode laser side-pumped diamond Raman laser, which comprises diode pumping laser, a first optical coupling module, a diamond crystal, a first Raman resonant cavity and a light shield, and is characterized in that the diode pumping laser is in continuous or pulse operation; after passing through the first optical coupling module, the laser forms a line focusing shape in the length direction of the diamond crystal to form a side pumping structure, residual pumping laser enters the light shield to be absorbed or scattered to guarantee safety, the first Raman resonant cavities are located on the two sides of the end face of the diamond crystal to provide positive feedback for Raman laser oscillation, and the second Raman resonant cavities are located on the two sides of the end face of the diamond crystal to form a side pumping structure. The excited Raman scattering light can be enhanced in the resonant cavity and forms stable laser output. According to the diamond Raman laser for diod
