NKT Photonics E15窄线宽激光器操作流程
Published on2026-04-17
NKT Photonics E15窄线宽激光器的操作流程主要包括硬件连接、软件设置与波长调谐控制三大部分，以下是基于官方技术资料整理的清晰操作步骤：硬件连接与接口说明在激光器后面板上找到 Modulation接口（9针D型接口），用于PZT波长调谐控制：Wavelength+（第9针）：接0~5V电压，使输出波长向长波方向移动。Wavelength−（第5针）：接0~5V电压，使输出波长向短波方向移动。地线（第2、4、6、8针）：任选其一接地即可，无需全部连接。注意：W− 和 W+ 上的电压不得超过 5V，否则可能损坏激光器。可使用直流电源或信号发生器进行测试，接线正确时，软件界面中的波长会随电压变化而实时更新。软件操作流程（Control Panel界面）打开控制软件，进入 Control Panel 界面。点击 Emission on 按钮，启动激光输出。若需调节波长，点击 WL mod 开启PZT波长调制功能。点击 Setting → Wavelength modulation，进入PZT设置界面：模式选择：Internal模式：由内部生成调制信号，可设置波形类型（正弦、三角等）、AC/DC耦合、调制频率与幅度。External模式：通过外部输入差分电压信号驱动，需确保输入信号与AC/DC模式设置匹配。调制范围：可选 Wide 或 Narrow，100%调制幅度对应 2×5 Vpp。Modulation Gain：可放大输入信号，但最大输出幅度不会超过设备标称值。安全提示：若不使用PZT调制，建议关闭“波长调制”功能，避免噪声引入额外相位抖动。波长调制工作模式说明DC耦合模式：适用于静态或缓慢变化的波长调节。AC耦合模式：具有 1.6Hz高通滤波 特性，适合动态调制，可滤除低频漂移。差分驱动（External模式）：Wavelength+ 与 Wavelength− 需施加共模电压 2.5V，差分信号驱动实现精确控制。
