I really need help!

Hi,

I have an 780nm 200mW NIR laser diode. It runs using 130mA and 2.4V. I want to house this in a Dorcy Jr. and i was wondering what resistor and silicone diode i should use to lower 300mA to 130mA and 3V to 2.4V. How should i connect it? in series or parallel? I would really appreciate an answer.

Thanks

BTW, here is the data sheet for the NIR laser diode: www.zet.biz/Laser/Data/gh0780ma2c.pdf

I have the same diodes you bought. I'm using it with these chips http://www.dealextreme.com/details.dx/sku.3160 and 2x18ohm .5W resistors in series with the LD. It burns and makes a visible red light.
