780nm Narrow linewidth laser

 780nm lasers are widely used in quantum computing, quantum precision measurement, optical precision measurement and other fields. As the product with the largest shipment volume and the richest models & categories at PreciLasers, this selection guide provides a systematic comparison of the full range of 780nm lasers from PreciLasers. For more information about 780nm laser solutions, please contact PreciLasers.

 
In addition to semiconductor lasers directly emitting at 780nm, all other 780nm lasers from PreciLasers are based on 1560nm narrow-linewidth seed lasers, 1560nm high-power amplifiers and frequency doubling modules. Two types of 1560nm narrow-linewidth seed lasers are available; their differences and selection details can be found in the document Comparison between Fiber DFB Seed Lasers and Fixed External Cavity Semiconductor Seed Lasers. Customized laser systems can flexibly adopt either fiber DFB seed lasers or fixed external cavity semiconductor seed lasers.
