Koheras HARMONIK High-Power Frequency-Doubled Laser System

The Koheras HARMONIK fiber laser system provides over 7 W output at 780 nm with a unique combination of low noise, narrow linewidth, and excellent beam quality. It is alignment-free and maintenance-free.

The HARMONIK system is a high-power frequency-doubled laser system consisting of our popular low-noise Koheras BOOSTIK HP fiber laser platform in combination with our new frequency converter module, HARMONIK.

The system gives you simultaneous power operation at the fundamental and second harmonic frequency. The C7 has an exceptionally low relative intensity noise: A RIN level of -140 dBc/Hz at 10 MHz. The E7 has a narrow linewidth and very low phase noise: A line-width of <0.2 kHz and phase noise of -87 dB((rad/√Hz)/m) at 10 Hz.

For both systems, the standard output power is greater than 7 W. It is possible to get above 7 W at 780 nm and 1560 nm or 766 nm and 1532 nm, simultaneously. If you need a higher output power, please contact us about custom power levels.Having a fiber-deliverable high-power source allows for multipurpose functionality.
