Optro先生
相干合成的困难似乎并不在理论上，低功率的相干合成系统能够很好验证理论的正确性，您说的工程上 ...
张老板，您找几篇低功率相干合成的论文出来，看他们是不是没有问题，你找出来一篇我分析一篇。 wang 发表于 2015-2-28 17:34 static/image/common/back.gif
新年新气象，老杜心态好很多了... 大家都加油
哈哈
我给一些人过了一个愉快的春节
我这个春节还没有结束，就遇到一件烦心事，天天去医院当陪护，一个老头了还去为人民服务。
2015年我的心情的确很愉快，我终于从理论上全面否定了相干合成的激光武器应用，据说有一篇几千瓦的论文自动撤稿。
我在今年，改变做法，邀请从事这个领域的人和我一起来否定他们曾经做过的研究，当然以前是错误的，我给你们机会。当然你们不愿意，哪我就不留情了，科学的真理不可以含糊。
我会对：
光纤激光
MOPA
波长合成等一一做理论分析，您们看作办。 Optro先生对MOPA有何理论分析，能不能简单说说您的结论？MOPA有问题吗？ 无知无畏 发表于 2015-3-14 09:40 static/image/common/back.gif

事情一步一步地走，先针对“相干合成”
从理论上否定这个课题是大事，全世界已经进行了10多年的研究，实际上一流的激光界的学者和世界上一流的实验室都参加了，就如一些人说的全世界都在做，都是这样做的，你也认为低功率已经成功，我就是这个项目公开否定的国内第一位。
我不需要喊口号，我用计算来证明，已经有一些人看到了，这个帖子，也基本说到了。 可以关注一下DARPA的一个光纤激光相干合成项目，不知道有没有进一步的信息可以查出来：
Title: FLASH - Scaling Fiber Arrays at Near Perfect Beam Quality
Description: The goal of the FLASH program is to demonstrate a transportable, packaged laser system whose output is derived from coherently combining the outputs of an array of ultra-lightweight, flight-worthy high power fiber lasers. The packaged FLASH laser system will project a >30-kW-class beam with near perfect beam quality and very high electrical-to-optical efficiency. The size, weight, and power (SWaP) will be consistent with weight and volume densities needed to support the integration of laser weapons on a broad range of Military platforms. To accomplish these ends, FLASH will (1) greatly reduce the overall size and weight of packaged coherently-combinable high-power fiber laser amplifiers while greatly simplifying the demands they make on support systems such as cabling, cooling lines and support structures while increasing their efficiency and resistance to shock, vibration and acoustics and (2) fabricate an array of these ultralight fiber-laser amplifiers and integrate them with advanced battery power, thermal management and coherent-beam combination sub-systems into a transportable, fully packaged laser system.
FY 2014 Accomplishments:
- Demonstrated a benchtop array of 1.3 kW fiber-lasers combined to produce a >30 kW near-diffraction-limited output at >25% electrical-to-optical efficiency.
- Estimated the capability of a 21-element optical-phased array system to compensate for atmospheric turbulence under various atmospheric conditions.
- Demonstrated target-in-the-loop phase-locking on a stationary target at a 7 km distance.
FY 2015 Plans:
- Develop and test a packaged, flight-worthy, coherently-combinable, fiber laser amplifier with an output power, beam-quality, size and weight consistent with system integration on tactical aircraft.
- Develop a preliminary design for a >30 kW, transportable, packaged laser system including fiber lasers, thermal management, power systems, and beam combination.
FY 2016 Plans:
- Develop a critical design for a >30 kW transportable, packaged laser system.
- Fabricate and /or procure parts and hardware for the >30 kW, transportable, packaged laser system.
- Assemble and test key subsystems for the >30 kW, transportable, packaged laser system.
- Begin the integration of key subsystems for a >30 kW, transportable, packaged laser system.
DARPA的项目看起来相当给力啊，国内加油！ 欢迎大家提供更多的光纤纤激光世界级的研究“成果”，特别欢迎张老板提供你说的光纤激光相干合成在低功率已经研究成功的作者和论文。
我再一次声明我否定相干合成不是针对一个个别的特例，是从理论上全盘否定这个课题，当然包括世界级的科研机构和重量级激光界的学者的这个课题的研究。
否定一个世界级的研究课题，没有充分的理论依据，只能是自己出丑！ Optro先生，您的目标定得太高了点，有点离谱。
理论上没法反驳相干合成，要想反驳只能在工艺和实现的难度上，实用性上。
OP加油 {:6_141:}杜大师加油啊
