Photonics & Laser Systems
Piezo subassemblies, cavity-locking hardware, ECDL support components, delay-line assemblies, and quantum-optics alignment hardware.
Hybrid Piezo + Titanium Scope
Photonics work spans heritage piezo subassemblies and titanium hardware. If a job needs both, the RFQ ties stack preload, mount stiffness, heat flow, cleanliness, and vacuum prep into one build record.
Solution Notes
Representative photonics applications we have integrated.
Stable Cavity Locking
Active stabilization of Fabry-Perot cavities using high-bandwidth piezo stacks.
Cavity locking demands sub-nanometer resolution with exceptionally high stiffness to reject mechanical noise. The actuator must respond instantaneously to the servo error signal while resisting thermal drift and acoustic vibration.
Key Specs
- Resolution: < 0.1 nm (electronics limited)
- Stiffness: 50 N/µm
- Resonance: 70 kHz
ECDL & Frequency Combs
Grating feedback tuning with hysteresis compensation and compact footprints.
External Cavity Diode Lasers rely on precise grating rotation or linear translation to tune wavelength. Frequency combs demand stability across the repetition-rate range. Compact 5×5 mm cross-sections allow dense integration behind gratings.
Key Specs
- Footprint: 5 × 5 mm
- Travel: 15 µm or 32 µm
- Voltage: -20 to 120 V
Optical Delay Lines
Precision path length adjustment for ultrafast diagnostics.
Pump-probe spectroscopy and ultrafast diagnostics need femtosecond-scale control of optical path length. Moving retroreflector or stage assemblies calls for higher blocking force than a simple mirror — 900N-class subassemblies maintain stiffness under load.
Key Specs
- Travel: 32 µm (nominal)
- Blocking Force: 950 N
- Capacitance: 3.1 µF
Quantum Optics Alignment
UHV-compatible stability for ion traps and cold-atom experiments.
Ion-trap and cold-atom experiments require alignment stability without contaminating vacuum or introducing magnetic interference. UHV preparation, non-magnetic options, and bakeout-survivable assembly are treated as quote inputs.
Key Specs
- Prepared for 10⁻⁹ hPa class vacuum
- Leads: Kapton / Teflon
- Options: Non-magnetic
Piezo stack plus titanium mount?
We have already built the piezo side. Send the titanium mount drawing and we will quote the combined build as one job when the scope fits.
