I have over 35 years experience as an electronic design engineer, please see my profile for more details The current price and timescales are only place holders to allow me to communicate with you I have already developed a laser pointer device triggered by blowing into a tube. Therefore your requirement is much simpler. If you write back I will send you photos of this design Best Regards Dave Lelievre

I have worked in fiber optics for many years. I have built several pointers for high visibility requirements. 300 ft in day light. I have designed visible light devices from 20mW to 10W. Both extremes are essentially useless. One can't be seen and the other burns out the diode in less than 60 minutes. I usually work with infrared diodes and communications. But a driver circuit for any diode is easy to deign and acquire. Depending on the diode I can have the part made in a few days to a week. I have drivers available to me. I don't have visible diodes. I think the smallest driver I have is about 10mm. I know size matters to you. You will have to determine what wattage or visibility requirements you want.
