Page 15: Description
Description The SuperK SELECT is a plug & play filter accessory for the SuperK series of lasers. The filter can tune and select multiple wavelengths from the emission spectrum of a SuperK laser. The SELECT also includes a range of unique features... -
Page 16: Aotf Crystal Types
AOTF crystal types The SELECT can be specified with a variety of AOTF crystals that can filter wavelengths from the SuperK emission spectrum from 400 to 2000 nm. Table 1 lists the crystal models available and the combinations which can be fitted in a dual AOTF SELECT. -
Page 17: Rf Driver
RF driver An NKT Photonics External RF Driver (ERD) unit is connected to the SELECT’s RF1 input. The ERD generates the necessary RF signals to drive a single AOTF crystal. The RF signals generated by the driver are configured to drive an AOTF for up to 8 output wavelengths. -

Page 31: Installation
General All chassis types must be installed on a level surface that is free from vibrations. The SuperK SELECT can be fastened to both metric and imperial optical tables. The ambient temperature surrounding the laser and SELECT system should be stable and free from anything that could cause temperature fluctuations. -
Page 32: Optical Connections
Optical Connections Caution: The SuperK SELECT is intended for use with the SuperK Class 3B and 4 lasers systems only. Using the SuperK SELECT with a laser source other than a Su- perK laser may result in hazardous radiation exposure. Warning: To operate these systems, you must be familiar with laser safety regula- tions and have received instruction in the safe use of lasers. -

Page 39: Output Power Considerations
Fiber Delivery If a fiber delivery system is mounted to the outputs of the SuperK SELECT, the single mode coupling acts as a spatial filter. In this case, no aperture in the beam path is required. Side lobe suppression will depend on the numerical aperture of the delivery fiber. -
Page 40: Optimum Rf Power
RF power. Note: The systems shipped from NKT Photonics A/S, have their optimum RF pow- er mapped as a function of wavelength. Your SELECT system RF level is already optimally mapped at the NKT Photonics factory and unless you swap-out certain hardware, no further optimization is required. -

RF cabling used between them. Figure 26 Wavelength versus optimum RF power level Remapping Since your SELECT system RF level is already optimally mapped at the NKT Photonics the Optimum factory, the following procedure is not necessary unless the original hardware has been swapped-out. -
Page 42: Beam Walk-Off
This mapping depends on the specific hardware configuration (driver, crystal and cables). If you decide to swap-out any part of your system’s factory configuration remapping may be required. NKT Photonics suggests you contact our support team before going forward with this procedure. -

Page 69: D Using A Superk Command Module
Using a SuperK COMMAND module Description A SuperK COMMAND is a multi-input module that connects to the RF driver of a SELECT system. The module accepts timing and modulation signals from external applications. These signals are then used to drive and synchronize fast wavelength switching and amplitude modulation of the output beam from the AOTF crystal of the SELECT system. -
