Dove prism
A Dove prism is a reflecting prism used for image reversal. A Dove prism is formed from a truncated right-angle prism. A beam of light enters one inclined face of the prism, is totally internally reflected from the longest (bottom) face, and then exits from the opposite inclined face. The image passing through the prism is flipped; since only one reflection occurs, the handedness of the image changes oppositely. Dove prisms have an interesting property: when they are rotated along their longitudinal axis, the transmitted image rotates at twice the rate of the prism. It is very important that applications must use parallel or collimated beams and keep the large square reflecting face very clean.

Laser pump sources are the core energy input component of solid-state lasers and laser amplifiers, and their performance directly determines the output power, beam quality and service life of the entire laser system. In scenarios such as industrial processing, scientific research experiments and high-end equipment, improper pump source selection will not only result in substandard system performance, but also bring a series of problems such as rapid device degradation and high operation and maintenance costs. This article sorts out the core selection logic and key pitfalls of pump source procurement, and provides selection references based on mature, mass-produced high-reliability products to help purchasers efficiently screen suitable products.
