IR Fiber Laser 974nm 680mW SM Fiber Coupeld Pump Laser FL-974-680-SM-B Desktop Type

The 974/976nm single-wavelength laser adopts a butterfly-shaped semiconductor laser chip with fiber FBG frequency locking. The professionally designed drive and temperature control circuit control ensures the safe operation of the laser and stable output power and spectrum. Suitable as a pump laser source for fiber lasers or fiber amplifiers, available in benchtop or modular packaging.

[Features]
1. High output power
2. Wavelength locking
3. Module or desktop package

[Applications]
1. Optical fiber laser pumping
2. Fiber Amplifier Pumping
3. Fiber optic device testing

Pump Protector

--

Not Include(Default)

If this laser is used as a pump laser,for Erbium-doped or Ytterbium-doped fiber laser.
We suggest adding protector, if not, it is easy to damage the pump chip.
Note:
1. Filter at 1030nm/1550nm.(choose)
2. The protector will cause the laser power loss of about 15~20%.
