Symphotony Co., Ltd. Begins Importing and Selling SISYPH Laser Diode Controller Products with Low-Noise Design for Quantum Computing Technology and Precision Measurement Applications

Symphotony Co., Ltd. has recently begun importing and selling laser diode controller products developed by SISYPH.

SISYPH, based in France, is a manufacturer specializing in equipment for precision measurement fields, including quantum computing technology. Their strength lies in their low-noise design, offering a range of laser diode control products.

**Introduction to Key Products Supporting Laser Control**

**<SK305 Aigoual (Linear TEC Driver)>**

**Function:** High-precision temperature stabilization of laser diodes.

**Features:** When combined with the "SK484 Temperature Controller," it achieves high-performance thermal stabilization. Its pure analog design enables low-noise operation by suppressing broadband noise.

**Specifications:** - True current source of ±1 A, compatible with digital control - Current limit function - Compliance voltage monitoring function - Noise density: 1 µA/√Hz or less, RMS noise: 100 µA or less - High current capability through parallel operation - Bandwidth: over 10 kHz - Analog design — configuration less susceptible to digital noise - Remote interface compatible - Supports standalone or platform operation

**<SK657 Gavarnie (Ultra-Low Noise Current Controller)>**

**Function:** High-precision current stabilization for laser diodes.

**Features:** It can control current with extremely low noise, suppressing fluctuations in laser output. It supports current control up to 500 mA and is equipped with DC modulation input and RF modulation input.

**Specifications:** - 500 mA current sink - Ultra-low drift: less than 10 ppm/K - Ultra-low noise: less than 10 pA/√Hz at 100 kHz - RF modulation compatible: 10 MHz to 200 MHz - High-speed modulation compatible: DC to 30 MHz - High current capability through parallel operation - Full remote control compatible - Supports standalone or platform operation
