Abstract

The invention relates to an optical-fiber side surface coupled laser diode pumped solid-state laser and a manufacture technology. The laser is characterized by comprising a laser medium and an output optical fiber, wherein the laser medium and the output optical fiber are fixed in a shell; one end surface of the laser medium is plated with a 1064nm total-reflection film and a 808nm total-penetration film; the end surface of the output optical fiber in the shell is plated with a 1064nm partial-penetration film and a 808nm total-reflection film; the end surface of the laser medium, which is plated with the 1064nm total-reflection film, and the end surface of the output optical fiber, which is plated with the 1064nm partial-penetration film, form a resonant cavity in the shell; one side surface of the laser medium is provided with a side-surface laser diode; the laser medium is subjected to cavity-outside pumping by the side-surface laser diode; and para-1064nm oscillation output is formed in the cavity. The optical-fiber side surface coupled laser diode pumped solid-state laser disclosed by the invention has the advantages of small volume, high reliability and high coupling efficiency.

technical field [0001] The invention relates to a laser diode-pumped solid-state laser, in particular to a fiber side-coupled laser diode-pumped solid-state laser and a manufacturing process. Background technique [0002] Laser diode-pumped solid-state lasers (DPL) usually output directly in the form of a window. In the process of using DPL, the beam is directly output, which limits the flexibility of laser use and the relationship between the laser and other equipment using DPL. Coupling connection between. [0003] The traditional DPL fiber coupling output method is to add a coupling device outside the DPL output mirror (or laser housing), couple the beam output through the window into the optical fiber, and then pass through the optical fiber and other optical instruments (or equipment) using DPL. It is difficult to adjust the coupling by this method, and the coupling efficiency is likely to decrease after long-term use, and the coupling needs to be re-adjusted. At the s...

[0003] The traditional DPL fiber coupling output method is to add a coupling device outside the DPL output mirror (or laser housing), couple the beam output through the window into the optical fiber, and then pass through the optical fiber and other optical instruments (or equipment) using DPL. It is difficult to adjust the coupling by this method, and the coupling efficiency is likely to decrease after long-term use, and the coupling needs to be re-adjusted. At the same time, the size, weight and appearance of the DPL are increased.
