976 nm 200W High Power Fiber Coupled Diode Laser HJK976BN1RN-200.0W
976 nm 200W High Power Fiber Coupled Diode Laser HJK976BN1RN-200.0W
Model: HJK976BN1RN-200.0W (ordering code K976BN1RN-200.0WN0N-10522F20)
The HJK976BN1RN-200.0W is a 976 nm wavelength-stabilized, high power fiber-coupled diode laser delivering 200 W into a 105 µm core, 0.22 NA fiber terminated as bare fiber or HP-SMA905. On-chip wavelength stabilization keeps more than 90 % of the power inside the 974.5-977.5 nm band, making it a stable pump source for high power fiber lasers. The package integrates an aiming beam, a monitor photodiode and a thermistor for temperature control.
Key Features:
- 976 nm wavelength
- 200 W output power
- 105 µm fiber core diameter
- 0.22 NA
Applications: Laser pumping; Scientific research
