Product Introduction

This is a 1457nm Raman Pump Laser Source with a fiber Bragg grating designed for Raman fiber amplifier and Er-doped fiber amplifier, a professionally designed drive circuit, and TEC control to ensure safe operation of the laser, stable output power, and spectrum. It can be provided in a desktop or modular package with an RS-485 communication interface and monitoring software for system integration. 400mW high output power. Please use with rated voltage, control temperature and humidity, ensure good heat dissipation, avoid output overload, and contamination.

Operation Steps

Step1.Unpacking: Before assembly, check whether all accessories are complete, including Pump Laser source module, USB data cable, power adapter, test report, etc.

Step2.Power supply: Connected to a DC switching power supply or a regulated power supply that meets their power supply requirements. Use only the original matched power adapter (DC5V or DC12V). Improper power adapters may damage the light source. (Power adapter supplied according to local voltage standards.)

Step3.Connecting output fiber: Open the dust cap at the fiber connector or flange, check the fiber end face, and connect the fiber or splice the fiber to the device or power meter to be tested after confirming that there is no pollution and damage.

Setp4.Connect to the host computer: Use the USB-RS485 DB9 Data Cable to connect the 1457nm Raman Pump Laser Source and the computer; the computer must first install a dedicated serial port driver to identify the USB-RS485 serial port data cable, otherwise the host computer software and the light source module cannot be correctly connected and communicated. Please ask Box Optronics for the driver.

Step5.Control software: Box Optronics provides the serial command or PC software to control the LD current and LD temperature of the 1457nm Raman Pump Laser Source. Choose the correct port, set the current and temperature, then click the open button. (To prevent damage, ramp up the drive current slowly at initial operation. Do not apply full current immediately.)

Step6.After use, click the close button, turn off the power supply, and disconnect the fiber connection.

Lead time

It takes around 10-15 working days for production. (If there are some in stock, it will be faster shipped.)

The international logistics might take 3-5 working days.

Operation Notes and Maintenance

● It is not recommended to frequently insert or remove the fiber optic connectors at both the input and output ends, in order to prevent dust contamination—which can lead to increased insertion loss—or the burning of the fiber connector end faces.

● Clean fiber connectors with a lint-free wipe and inspect with a fiber end-face detector before connection. Always connect/disconnect fibers without power to avoid end-face burning. The fiber optic connectors must be covered with dust caps.

● If the output fiber needs to be connected to another fiber, it is recommended to use a fusion splicer.

● Please take precautions against moisture, dust, and corrosion; store in a dry place.

Quality Assurance and After-Sales Service

● Warranty Period:

Free repair or replacement for non-human-induced defects within 1 year from purchase. Paid maintenance services available after 1 year.
