The LD-PD'S FM-DCFL Series 1550nm fs Er doped Dual Channel fiber lasers. It is an excellent solution for industrial terahertz femtosecond pump source applications. The femtosecond laser has the typical advantages of traditional fiber laser, namely, small size (shape size: 200 *100 *40mm), no need of thermal management, and high output beam quality (single mode output).
This ultrafast laser has spectral center wavelength at 1550 nm, the repetition frequency is 20-100 MHz, typical pulse width is less than 120 fs, and the maximum average output power of each channel is 32 mW. Due to the use of special non-linear technology to achieve the equivalent saturable absorber effect, the output pulse not only has high long-term stability, but also can withstand high and low temperature working environment from 0-45 degrees.

Safety and Operating Considerations
The laser light emitted from this laser diode is invisible and may be harmful to the human eye. Avoid looking directly into the fiber when the device is in operation.
CAUTION: THE USE OF OPTICAL INSTRUMENTS WITH THIS PRODUCT INCREASES EYE HAZARD.
Operating the laser Components outside of its maximum ratings may cause device failure or a safety hazard. Power supplies used with this component cannot exceed maximum peak optical power.
