The HARMONIK system is a high-power frequency-doubled laser system consisting of our popular low-noise Koheras fiber laser platform, BOOSTIK, in combination with our new frequency converter module, HARMONIK.
Depending on your need, choose from two HARMONIK systems, the C7 or the E7.
The C7 with low relative intensity noise
The C7 has an exceptionally low relative intensity noise: A RIN level of -140 dBc/Hz at 10 MHz.
The E7 with narrow linewidth and low phase noise
The E7 has a narrow linewidth and very low phase noise: A line- width of <0.2 kHz and a phase noise of -87 dB(rad/√Hz/m) at 10 Hz.
High standard output power and excellent beam quality
For both systems, the standard output power goes up to 7 W. If you need a higher output power, please contact us about custom power levels.
The excellent beam quality, M2 < 1.1, is suitable for cutting edge quantum physics projects such as quantum sensing and laser cooling and trapping, to mention a few.
Free space or fiber output in a robust packaging
As default, the HARMONIK systems come with free space output. If fiber coupling is needed, we can propose an efficient coupling via our unique polarization-maintaining single mode photonic crystal fiber that ensures high-power delivery.
The BOOSTIK system is delivered in a turn-key 19″ rack system and the HARMONIK is a table top module.
