Chapter 1 Introduction The GSL series of lasers provide picosecond, nanosecond, and continuous wave operation in a compact, fiber- coupled, turnkey source. Gain-switched pulse generation with repetition rate control up to 200 MHz and adjustable pulse widths allow for applications including high-speed imaging and fluorescence lifetime measurements.
If equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. Only with written consent from Thorlabs may changes to single components be carried out or components not supplied by Thorlabs be used.

However, there is no guarantee that interference will not occur in a particular installation. Thorlabs is not responsible for any radio television interference caused by modifications of this equipment or the substitution or attachment of connecting cables and equipment other than those specified by Thorlabs. The correction of interference caused by such unauthorized modification, substitution or attachment will be the responsibility of the user.
Note: For repetition rate setting “A” and “B” there will be no optical output unless the laser is triggered. Emission LED Figure 2 GSL Series Laser with Fiber Patch Cable Connected to Output Page 4 TTN311232-D02...
1, 10, 100, and 200 MHz. Figure 3 Block Diagram of the GSL Series Laser Head Power Power is supplied by the external, +15 V, wall-mounted DS15 Power Supply included with the unit and shown in the left image of Figure 4.

Use the included 2.5 mm flathead screwdriver to operate these controls. All of the GSL series offers controls for varying the pulse width. Use the included 2.5 mm flathead screwdriver to operate this control also, as shown in Figure 7. The range of pulse widths for each model are listed in the specifications table in Section 5.1.
