The following accessory is offered.

TeraSpike Defender

The TeraSpike Defender is an optional housing protecting the sensitive tip of the probe against accidential mechanical impact. The exposure of the tip can be manually adjusted from -1mm to +1mm. In the negative exposure range a direct contact of the probe-tip to a flat surface is prevented by the TeraSpike Defender housing. Optical excitation as well as visual monitoring of the tip region is not impaired by the protective structure thanks to vertically placed openings. The TeraSpike Defender can be applied to any existing or new TeraSpike probe.

SHG Unit 500

The new SHG-Unit from Protemics is an easy to operate and very efficient solution to convert IR light from cost-efficient femtosecond fiber-lasers into NIR light for the high-efficiency excitation of our LT-GaAs-based TeraSpike microprobes and TeraBlast emitters.

Key benefits:
  • Recommended for TeraSpike microprobe operation with IR femtosecond lasers
  • High power conversion efficiency
  • Passive and robust design
  • Short warm-up time(10-15 min)
  • Can be configured for free-space (-FS) or fiber-coupled input beams (-FC)
  • Easy to use and integrate

The TeraSpike Phantom is a dummy device for the replacement of a microprobe during construction work and system development. The use of the TeraSpike Phantom - as also included in the starter kit - is recommended to avoid the risk of an uncontrolled mechanical impact in critical working situations.
