780nm Single Frequency Fiber Laser
Product Description:
Connet 780nm Single Frequency Fiber Laser is one narrow linewidth frequency-doubled single frequency fiber laser. The laser consists of two parts: 1560nm high power narrow linewidth single frequency fiber laser and high efficiency frequency doubling unit. These two parts are connected by optical fiber. The standard polarization-maintaining fiber is normally adopted for output. The output beam quality is excellent and the product is easy to operate.
Based on the built-in 1560nm single frequency fiber laser, the 780nm single frequency fiber laser can achieve the real single frequency, single longitudinal mode and linear polarization output. The frequency doubling unit adopts the Periodically Polarized Lithium Niobate (PPLN) Technology. The 780nm laser maintains the low-noise performance of 1560nm single frequency fiber laser. The output power of the 780nm single frequency fiber laser can be up to 2W. The output linewidth of the 780nm single frequency fiber laser is optional in <20kHz or <5kHz based on the different built-in laser models.
