Page 3: Description
Description The Thorlabs Fiber Coupled Laser Sources are fiber optic laser sources that provide ease of coupling and simple control of laser diode driven fiber optics. These laser sources are available in two versions, Fabry- Perot and Distributed Feed Back (DFB). The Fabry-Perot version comes in five available wavelength choices from 635nm up to 1550nm. -
Page 4: Setting The Ac Line Voltage And Installing Fuses
Setting the AC Line Voltage and Installing Fuses Your S1 or S3 Series Laser Source has been shipped from Thorlabs, Inc. configured for 115VAC operation. If you are planning to operate your unit using a 220 / 230VAC input, or need to replace an open fuse, you must perform the following procedure: Remove any AC Input cords that may be connected to the unit. -

2) Turning ON the Source Turn the POWER keyswitch clockwise. The unit is ON when the 3 ½ Digit Display lights up. Make sure the Interlock Input is short-circuited, refer to “Making the Safety Interlock Connections”. Press and release the ENABLE switch to turn ON the laser. Immediately the LASER ON indicator will light up, after a “safety delay”... -

Page 8: Adjusting The Laser Output Power
The MOD IN input can be used to sinusoidally modulate the laser output, or set the laser output remotely using a 0 to 5V power source. The 5V maximum input corresponds to the maximum calibrated power of the S1 Series Laser Source, which operates using a constant power drive technique. The S3 Series DFB Laser Sources operate using a constant current drive technique, which causes the actual output power to be dependent on the operating temperature as set using the TEMP ADJ pot. -

Maximizing the Stability of the S3 Series DFB Laser Source The S3 Series DFB Laser Source provides the ability to control not 75% Current 1547.993nm only the output power of the fiber coupled laser diode, it also allows for the precise control of the temperature at which the laser is operating. These two controls can be used to “tune”... - Page 11 How to tune your Laser Source to the most optimum power: So what does all this mean? It means that through careful use of both the laser diode power control and laser diode temperature control you 24.3 C will be able to tune your unit to provide the most stable output. Ideally 1547.994nm this procedure should be done using an Optical Spectrum Analyzer (OSA), however, lacking one you should be able to tune the unit using...
