- Page 7 3 Laser safety operating instructions 3.1 Laser usage requirements in environment A ultra-clean environment should be provided for operating the LD. The operating temperature should be controlled at –10 °C … 45 °C. Laser safety warning signs should be posted in the working place. 3.2 The requirements on the power supply driving the LD ...
- Page 8 The operating current of laser must not be higher than the given rate current. The excessive current would accelerate aging and shorten lifetime, even damage the LD. Keep the fiber pigtail clean. In non-working environment, you must use the protection case to avoid fiber pigtail from being polluted.
- Page 9 Short-circuit bridge When laser is working, please don’t point it straight to the fiber as shown below the yellow part, in order to prevent the fiber protection case from being damaged by high- power laser generated heat. Bending diameter of the fiber cannot be allowed to be less than 4cm. When bending the fiber, please make sure the starting point is away larger than 4cm from the fiber root.
- Page 10 × 3.4 Cooling system High-power semiconductor Laser Diodes are temperature-sensitive devices. High temperature will affect its performance. Its lifetime may also be shortened by working at high temperature. So the generated heat must be removed in time when the LD is working. Water cooling system or TEC system is recommended for keeping the LD working at appropriate temperature.
