of pump laser. As shown in Figure (2)
6.8.1 Pump Switch State: If there is no light power input, pump will keep close.
Figure (2)7.1.
6.8.2 Lead Pump Bias: Figure (2) 7.2, displaying LD bias currents in laser.
When the operating current is greater than 130% of rated current, the working life of
laser are affected, even damage the lasers. Therefore, when detected laser operating
current is greater than 130% of rated current. The internal hardware circuit of
equipment has limited its scope.
6.8.3 Lead Pump Temperature:
lasers work properly at 20
℃
~35
℃
temperature range. 6.4 in Figure (2) 7.3.
LCD displays the actual temperature of
laser, such as "25.5
℃
", when the detected
temperature is 20~30
℃
, the LCD displays
real-time temperature.
6.8.4 Laser Cooling Current:
in Figure (2) 7.4. In order to ensure the
internal temperature of laser range from
20
℃
to 30
℃
, we should provide Thermoelectric cooling device a certain amount of
operating current. When the detected working current of thermoelectric cooling device
is within-1500mA~ +1500 mA, the LCD displays real-time current. When the current is
positive, the TEC cool.
6.8.5 Multi-pump Current: Figure (2) 7.5.
6.8.6 Multi-pump Temperature: Figure (2) 7.6.
