(1)XXXX is the laser center wavelength，YY is the laser power，for a 6W 770nm laser,the partnumberis FL-SF-770-6-CW
(2)If the laser output power ≤2W, the PM fiber output version can be choosed
(3)Beam diameter is only applicable to free space output mode，For PM fiber output mode，the fiber without collimator
(4)Measured by self-hetrodyne method
Higher power, more wavelengths, customizable solutions
