Page 14: Introduction
Sepia PDL 810 Manual 2. Introduction The Sepia PDL 810 system is a single channel pulsed diode laser driver system that allows operating a con- nected laser head in either pulsed or continuous wave (cw) mode. The driver may trigger the laser au- tonomously from its built-in crystal oscillator or, if a more complex triggering scheme is needed, can also be triggered by an external signal. -
Page 15: Installation And Quick Start
Hardware Installation When selecting a location for the Sepia PDL 810, please ensure that sufficient air flow from the fan at the rear panel is available by keeping a distance of 10 cm to any obstacle. The venting slits at the bottom must not be covered. - Page 16 2. a computer to install and run the operation software. The computer needs to have a free USB slot as well as a Windows operating system. Place the Sepia PDL 810 on its dedicated place, insert the power cord and connect the Sepia PDL 810 to the host computer using the delivered USB cable.

The GUI shows the control panel for the installed laser driver to the right side as shown in Fig. 12 (item Triggering Modes The pulse repetition rate of the Sepia PDL 810 can be derived either from its internal crystal oscillator or from an externally supplied trigger signal. The triggering source can be selected from the drop down menu labeled Trigger Source. -
Page 19: Hardware Description
4.1. Startup Operation At power up, the Sepia PDL 810 performs some basic checks on its hardware before the system is ready for operation. Once these tests are successfully completed, the “STATUS” indicator emits constant green light and the laser driver will operate according to its last settings. -

Page 31: Application Hints
PicoQuant GmbH Sepia PDL 810 Manual 6. Application Hints 6.1. Choosing the Correct Laser Intensity To ensure safer working conditions and to prolong the lifetime of the laser element, select a lower power set- ting (approx. 35% of full power). Full laser power should not be used unless it is absolutely needed. This ap- plies especially to laser diodes in the ultraviolet to blue region, which still have a shorter lifetime than red or infrared laser diodes. -
