Page 11: Harmonik System Description
HARMONIK System Description The HARMONIK system is a high-power frequency doubled laser system. The system is modular and consists of the following modules: Optical module – the module houses the HARMONIK’s optical components • for frequency doubling the source laser beam. Specifically, this is a photonic crystal operating at 50-65°... -
Page 12: Optical
Optical Optical Emission beam The beam quality, M2 is less than 1.1 and is suitable for advanced quantum physics quality projects such as quantum sensing and laser cooling and trapping. Contact NKT Photonics to discuss the applications that are possible. Free-space or fiber By default, the HARMONIK systems are equipped with free-space output apertures. -

Optical module Optical module Front panel The optical module front panel houses the electrical interfaces and an optical input assembly in a cut-out along the front and right side panel as shown in Figure Figure 3 Optical module front panel Caution: DO NOT REMOVE or LOOSEN the screws marked with the Caution symbol in this image. -
Page 15: Rear Panel
Optical module Caution: Under no circumstances should the collimator assembly be disassem- bled by unscrewing the collimator clamp screws. Optical input aperture The emission from the BOOSTIK HPA is coupled through the collimator assembly to the optical input aperture from the factory aligned collimator assembly. Rear panel The rear panel houses two free-space output apertures. -

Page 21: Optical And Control Module Installation
Optical and Control Module Installation General All modules types must be installed on a level surface or rack that is free from vibrations. The ambient temperature surrounding any of the optical modules should be stable and free from any sources that could cause temperature fluctuations. -
Page 22: Electrical Supply Requirements
Installing the system Electrical Supply Supply voltage is 100-240 VAC, maximum 100 W Requirements Installing the system The optical module is designed to be fastened on an optical table with M6 holes spaced apart by 25 mm. Alternatively the module can be clamped to any table using the four clamp slots available on both the left and right panels. -
Page 23: Control Module
The control module can be placed on any surface nearby the optical module such that the communications and power cable between it and the optical module is not excessively bent or stretched.

Page 29: Turning On The System
Turning on the system selected, click the Start Upgrade button and wait for the upgrade to complete and the system to reboot. Figure 13 Settings page (expanded) Turning on the system Turn on the DC power by pressing the power switch on the front panel of the Control module. -
Page 30: Setting The Ip Address
Connecting to the HARMONIK Note: The module can also be connected to either: a. a local L2 switch where the PC is also connected. b. a correctly configured IP subnet which is reachable from the PC. (Note that step 2 may not be necessary in this case.) 2. -
Page 31: Resetting The Ip Address To Default
Connecting to the HARMONIK 2. Under Connection–Address settings (see 15), either: Figure a. Check the Activate DHCP check box - this configures the HARMONIK system as a DHCP client to automatically assign it an IP address from a DHCP server. - or - b. -
Page 32: Using The System
Using the system Using the system Initial use When starting up the Koheras HARMONIK system for the first time: Set the fundamental input power from the BOOSTIK HPA amplifier to a low value i.e. P < 1 W – see document: Koheras BOOSTIK HPA Product Guide 2. -
Page 33: Auto Temperature Button
Using the system Warning: Depending on temperature setpoint optimization, almost the entire fun- damental input power is transferred to the fundamental laser output. Optimize the second harmonic emission level Turn on the system, enable emission and allow the HARMONIK crystal to warm-up until the temperature in the Temp set field stabilizes –... - Page 34 Using the system Patch cable connector cleaning Due to the high power transmitted through the single mode fiber surface of the optical connector(s), it is important to keep all connector faces extremely clean. This is particularly important for amplified systems, where the power level is high.
