pump housing:
Figure (3) page "1" and page "3".
4.5.2) fan status:
Figure (1) page"4" . The fan, a total of three kinds of working state can be
adopted .In the current page, click the"
"key to change the working state, while in the "AUTO"
state, when the device internal temperature is higher
than 35
℃
, the SCM will automatically open the
chassis fan to cool, and it will not close until the
temperature dropped to 30
℃
.
4.6) query the parameters of pump laser:
Figure (1) page "6". In the current page click the
button "
" to query the parameters of pump laser.
As shown in Figure (2).
4.6.1) Pump laser bias:
laser 1, 2, 3
bias, 6.1,6.2,6.3 in Figure (4), shows the
bias current of the LD within the current
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. When the bias current directives is "----", it states that
the pump laser was not be used.
Temperature and cooling current show similarly.
4.8.2) Laser Temperature:
lasers work properly at 20
℃ ∽
35
℃
temperature range. 6.4
in Figure (4). LCD displays the actual temperature of laser, such as
"25.5
℃
", when the detected temperature is 20
℃
~ 30
℃
, the LCD
displays real-time temperature.
4.8.3)
laser
cooling current:
6.5 in Figure (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.
