J40 power supply

[rossler]

I have UV laser with J-series power supply. mabye it is called J40
power supply.

Now the output power is low, so I want to check the diode power itself
without laser head.

But there are many interlocks, so if possible, I would like to know
how to handle the power supply itself to remove the several
interlocks.

Does anybody know how to do it?

Regards,

Myungwoon Kim

Isn't this fiber-coupled to the laser head?

Can't you just disconnect the fibers from the laser head and measure
the pump power there?

Sam is right...just disconnect the fiber from the laser head (be carefull
to keep it very clean)
and measure the power there.

What kind of laser / laser head head do you have?
