摘要
制备了用于固体染料激光器的高分子共聚物基体,研究了两种激光染料Rhodamine-B(Rh-B)和Pyrromethene 597(PM-597)在高分子基质中的光谱性质。以调Q的Nd:YAG激光器的倍频光为抽运光源,在无外加谐振腔的条件下Rh-B和PM-597掺杂的高分子基体中获得了高转换效率和大能量激光输出,可为固体染料激光器的实用化提供关键工作物质。
Abstract
Rh-B and Pyrromethene-597 laser dyes were successfully introduced into copolymer matrices of 2-hydroxypropyl methacrylate and methyl methacrylate. The spectral properties of two copolymer dye lasers were studied in the present paper. Pumped by a second harmonic Q-switched Nd:YAG laser (532 nm), laser oscillation was achieved in the well-polished φ25 mm×25 mm cylindrical Rh-B and PM-597 copolymers without resonance mirrors. It is found that in Rh-B doped copolymer, slope efficiency and center lasing wavelength was 35.3% and 590 nm, respectively. While in PM-597 doped copolymer, 62.2% slope efficiency and 585 nm center lasing wavelength were detected. The laser damage threshold was 62.5 MW/cm2 for Rhodamine-B doped laser and 200 MW/cm2 for Pyrromethene-597 doped laser.
