3 SPA Beam Expander The innovative SPA Beam Expander, consisting of one or more aspheric beam expanders, is the right choice when it comes to high-power beam expansion with outstanding quality. Highest accuracy and diffraction-limited performance thanks to an aspheric lens individually measured and certified. Choose between five design wavelengths [355 nm / 532 nm / 632 nm / 780 nm / 1064 nm] and achieve up to 32x diffraction-limited beam expansion. NEW: Benefit from beam expansion optimized for Nd:YAG laser [355 nm] with the brand-new SPA Beam Expander UV made of Suprasil. Technical dimensions [mm] = Monolithic beam expander with just one aspheric lens for the highest level of precision = Available with expansions of = Possibility of combining up to five expanders for up to 32x beam expansion and over 230 intermediate stages = Completely diffraction-limited with up to five expanders individually measured and guaranteed by an original asphericon certificate = Laser induced damage threshold: 12 J/cm², 100 Hz, 6 ns, 532 nm SPA Beam Expander [ nm] SPA Beam Expander UV [355 nm] = Intelligent assembly concept for easy handling SPA Waveλdapt Applying the corresponding SPA Waveλdapt, the SPA Beam Expanders can also be used with wavelengths other than one of the four basic wavelengths [532 nm / 632 nm / 780 nm / 1064 nm]. The SPA Waveλdapt adjusts the divergence and corrects the wavefront deformation while retaining the beam diameter. Technical dimensions [mm] = Optimized adaptation to any wavelength from 500 nm to 1600 nm 49.2 to 51.1 = Combinable with up to five SPA Beam Expanders completely diffraction-limited = Preservation of adjusted magnification = Easy and flexible handling = Compensation of divergent incoming beams up to 1 mrad

4 Effect on ultrashort laser pulses Wavelength range Broadening of a femtosecond pulse after propagation through one SPA Beam Expander for a wavelength range from 500 nm to 1600 nm. Output pulse duration [fs] Covered range of wavelengths for the design wavelengths 532, 632, 780, 1064 nm when using the attendant SPA Waveλdapt. Design wavelength [nm] Input pulse duration [fs] Wavelength [nm] 1500 SPA AspheriColl NEW The SPA AspheriColl is an adjustable fiber collimation package and the latest addition to the SPA Beam Expander Kit. Choosing from the two available focal lengths the basic beam diameter is set as shown in the graph below. Combining this element with SPA Beam Expanders generates any desired output beam diameter while maintaining a diffractionlimited wavefront. Technical dimensions [mm] = Flexible choice of output beam diameter in combination with SPA Beam Expanders = Simple mounting to SPA Beam Expanders via metric fine thread = Always perfectly aligned lateral position = Completely diffraction-limited performance (Strehl > 0.95) when used with FC/PC patch fibers individually measured and guaranteed by an original asphericon certificate = Optimized for all wavelengths [500 nm to 1600 nm] FC/PC connector 33.4 Output beam diameter Wavelength range Collimation of output from single mode fiber with NA 0.12 to 0.35; pre-aligned for 532 nm, 632 nm, 780 nm and 1064 nm Beam diameter [mm] EFL = 20 mm EFL = 10 mm Numerical Aperture (NA) Covered range of wavelengths of the SPA AspheriColl for the design wavelengths [nm] 532, 632, 780, Design wavelength [nm] Wavelength [nm] 1500

5 SPA Adapter Connect the SPA Beam Expanders conveniently and easily with the matching SPA Adapter intra-system in order to be able to use it in both functional directions (expansion or reduction of beam diameter). The cross-system adapters (C-Mount, SM1, 1.2 circumference) guarantee a high level of compatibility with the setup of other optical systems without additional adjustment. SPA Adapter intra-system SPA Adapter cross-system (female/female and male/female) SPA Adapters cross-system = Easy combination of SPA Beam Expanders by using asphericon intra-system adapters = Easy integration of the SPA Beam Expander into any optical system through a variety of mounting concepts by using asphericon cross-system adapters Adapter type Product code Thread type 1.2 circumference UAM in-MII female/female C-Mount male UAM25-28-C-MIO female/male C-Mount female UAM25-28-C-MII female/female SM1 male UAM25-28-SM1-MIO female/male SM1 female UAM25-28-SM1-MII female/female Key features Certificate SPA Beam Expander Configurator For each component of the SPA Beam Expander Kit a certificate based on wavefront measurement guarantees diffraction-limited performance.
