<p>A miniature laser tube of a semiconductor laser pump comprises a main body base (1), a rectangular column body (2) disposed on the main body base (1), and a binding post (8) connected below the main body base (1). The main body base (1) and the rectangular column body (2) are in integrated mechanical connection. An 808-nm laser pump light source (3) and a YVO4+PPLN laser crystal (4) are successively disposed at the upper portion and the lower portion of the inner side of the rectangular column body (2). A PD light receiver (5) is disposed on the main body base (1). In addition, the miniature laser tube of the semiconductor laser pump comprises a metal protection case (6) sleeved on the main body base (1). According to the miniature laser tube of the semiconductor laser pump, by reducing outline dimensions of a 532-nm laser in the prior art, the miniature laser tube of the semiconductor laser pump has a compact structure and reasonable design, the 532-nm pump laser microminiaturization is successfully implemented, and the reliability and stability of the performance of the laser tube are improved, thereby meeting current demands for this kind of the laser tube on the market.</p> |
