Thorlabs' 4-Channel, Fiber-Coupled, Customizable Laser Source provides easy coupling and simple control of laser-diode-driven fiber optics. The laser source is configured to accept a wide range of fiber-pigtailed laser diodes with discrete wavelengths in the spectral range from 405 - 1550 nm, in any combination. The laser source allows more than one channel to be turned on simultaneously; however, it is only possible to adjust the power output of one at a time from the front panel.

Each laser diode is operated from an independent, high-precision, low-noise, constant-current source and temperature control unit. An intuitive LCD interface allows the user to view and set the laser current and temperature independently for each laser. The display indicates the channel number selected, the output wavelength of the source, the operating power calculated from the laser diode monitor diode, and the actual temperature the laser is set to.

This device incorporates a microcontroller to fully control the laser's optical power and temperature as well as to monitor the system for fault conditions. The laser source includes a USB connection that allows remote enabling, power adjustment, and temperature adjustment. On the rear panel, analog inputs are available to modulate the laser diodes' outputs with an externally generated waveform. To prevent damage, the microcontroller will disable the output if the sum of the analog input and internal set point exceeds the laser limits.

Safety
While most output sources fall within the class 3R laser rating, the system was fully designed to meet laser class 3B requirements. There is an interlock located on the rear panel that must be shorted in order for any laser output to be enabled. This can easily be configured to be triggered by doors to disable the lasers in unsafe conditions. The power switch is a keylock system to prevent accidental or unwanted use. Each source has its own enable button allowing the user to choose the light source or sources he wishes to be active, as well as a master enable that must also be set. Each channel includes a green LED indicator to easily determine its current state. There is a 3 second delay before the lasers turn on, and the user is warned by the LED rapidly blinking.

In the Box
The MCLS includes a universal power supply allowing operation over 100 - 240 VAC without the need for selecting the line voltage. The fuse access is conveniently located on the rear panel. This unit is supplied with a U.S. line cord as well as a standard European line cord, the pre-configured MCLS1 with all selected lasers installed, and the manual.

Below is a list of available lasers listed by wavelength and showing the corresponding minimum output power and pigtail fiber type. To discuss potential custom wavelengths and configurations not available below, please contact us. Please use the configurator below to select the pigtails and locations you would like. Note: If you leave a channel blank, the unit will be shipped without a laser in that channel. Thorlabs will fill the empty slot at a later date if you desire. Please contact Tech Support prior to sending your unit back to us.
