Normal procedure

In the operation mode, each diode laser is in lasing mode rendering an output power of approximately 30 W. The laser beam is already aligned, properly focused and directed into the pumping cell. The lasers are interlocked with the entrance door of the laser hut. All the laser beam pipes and the laser enclosure on top of the target are securely installed.

Working with the lasers in normal operational mode will require protective eye wear with a minimum optical density (OD) of 4.7 at wavelength of 795 nm. Before starting the laser in its normal operation mode personnel have to enable the laser safety interlock box. This will cause access to the laser hut to be in a controlled mode. Authorized personnel with an access code can bypass the interlock for 45 seconds when entering the laser room. Unauthorized personnel entering the room will cause the lasers switching to stand-by mode when the door is opened. If the laser is to be unattended for a long time, the power should be switched off.

Thus the general procedures for normal operation of the diode lasers in the target lab are:

• Enable laser safety interlock box;;
• Wear protective eyewear;
• Switch on AC power;
• Turn on the control box with a key;
• Turn laser to Ready and then On.
