摘要 | A pulsed fiber laser and associated electronics contained in a miniature package is disclosed. The Pulsed Fiber Laser Source (PFLS) can be a single-stage high gain master oscillator power amplifier (MOPA) type fiber laser source. The PFLS can include a distributed feedback (DFB) laser, a narrowband optical filter, a broad area high-power pump diode, and Erbium/Ytterbium (Er/Yb) double cladding doped fiber. Input electrical pulses drive the DFB laser diode to emit optical pulses that are then amplified by the optical amplifier. Active and passive cooling elements may be incorporated for continuous operation without rest time. Passive cooling for intermittent pulsed applications allows the laser source to be miniaturized by eliminating active cooling elements and associated power supplies and controllers. Low duty cycle relaxes drive requirements and further reduces the size. The PFLS can be used for long distance ranging, communication by retro-modulation, and communication in presence of atmospheric attenuation. |
其他摘要 | 公开了一种包含在微型封装中的脉冲光纤激光器和相关电子器件。脉冲光纤激光源(PFLS)可以是单级高增益主振荡器功率放大器(MOPA)型光纤激光源。 PFLS可以包括分布式反馈(DFB)激光器,窄带光学滤波器,宽区域高功率泵浦二极管和铒/镱(Er / Yb)双包层掺杂光纤。输入电脉冲驱动DFB激光二极管发射光脉冲,然后由光放大器放大。可以结合有源和无源冷却元件用于连续操作而无需休息时间。用于间歇脉冲应用的被动冷却允许通过消除主动冷却元件和相关的电源和控制器来使激光源小型化。低占空比放宽了驱动要求并进一步减小了尺寸。 PFLS可用于长距离测距,通过逆向调制进行通信,以及在存在大气衰减的情况下进行通信。 |
