Nanosecond pulse laser (523 nm, 1 ns, 6 kHz), Nanolase, Model: NG-10320-T04 (JDS Uniphase)
It emits bright green laser pulses when connected to a current source.
The current source in the first photo is NOT included.
So, you need to prepare an appropriate current source to drive a laser diode inside the laser head. I usually operate it at 700-900 mA.
It will be shipped from Japan via EMS of Japan Post.
The international shipping charge will be about $70 to US.
