Optical Frequency Discriminator

OFD_003
c_OFD_2b

The OFD system smartly delivers a voltage signal that is proportional to the frequency fluctuations of the input laser beam. This turn-key module is suitable for laser frequency noise characterization and/or for laser frequency stabilization to drastically reduce its optical “full width at half maximum” linewidth. The OFD features ultralow noise performances, successfully achieving a frequency noise level as low as 0.01 Hz²/Hz. All this in a compact and user-friendly package.

 

ULN-PDB

sec_photonics_b

The ULN-PDB module is a plug and play Ultralow Noise Balanced Photodetector in a compact and user-friendly package. It offers the best performances in terms of signal-to-noise ratio. ULN-PDB is proposed with InGaAs or Si photodiodes (with FC connectors) and offers a bandwidth of 100 MHz with a high gain of 39 kV/A in a DC-coupled configuration.

SLIM LINER

SL_003
c_SL_2

The SLIM LINER – High spectral purity laser source - is a single-frequency, ultra-narrow linewidth laser is based on a Self-Adaptive Photonic Oscillator (SAPO) technology developed by the Institut Foton at Université de Rennes in France. A pump laser is locked onto a cavity using stimulated Brillouin scattering that offers an extremely narrow gain bandwidth, naturally favoring a high spectral purity.

 

ELECTRONICS

SILENTSYS proposes different electronic modules that aim to improve your setups, experiments and systems.

PID-01

PID01_003
c_pid4

The PID-01 is a High-Speed Servo Controller. It is digitally controlled using an integrated touchscreen and provides Proportional, simple Integrator and double Integrator functions. It features ultralow noise, more than 200 dB open-loop gain, and a bandwidth of >30 MHz.

 

FIL-01

sec_elect_b

The FIL-01 is an electronic high-pass filter and amplifier module developed to offer the best performances in terms of voltage noise characterization. FIL-01 acts as an AC coupling filter by removing the DC component of the input signal with a cut-off frequency of 600 mHz. The output signal is also amplified by a factor of 2000 (66 dB amplification) with a 3MHz bandwidth and an input voltage noise of 0.6 nV/√(Hz)

ALM-X

ALMX_003
c_ALM_2

The ALM-X are power supply modules.

They have been developed to offer the best performances in terms of output voltage noise and stability. ALM-01 offers 3 ultralow noise output voltages (standard version 5VDC, 12VDC and 15VDC) with up to 25 W in total, ALM-05 offers a 5VDC voltage output with a maximum of 3A, and ALM-08 provides two voltages : a 2VDC output at up to 8A and a 5VDC output at up to 1A.

THz/GHz

 We provide laser frequency stabilization/down conversion systems that enable low-noise THz or GHz signal generation.

Optical Frequency Correlator

OFC_003
c_OFC_2

The OFC system is composed of a common 2-input optical frequency discriminator (OFD). This makes it possible to frequency stabilize two wavelength distant lasers onto the same optical reference in order to reduce their frequency fluctuations and to correlate them precisely.
Based on this fact, the optical beat frequency between the two stabilized lasers generates THz or GHz signals that reach a very low frequency noise level and are easily frequency tunable.
Moreover, as a standard OFD, it smartly delivers a voltage signal that is proportional to the frequency fluctuations of the input laser beam. This turn-key device is suitable for laser frequency noise characterization and/or for laser frequency stabilization.
