How to build driver for laser diode with using only 2 AA batteries suply (as in most common laser pointers) which gives me only 2.4 V (NiMH) or 3V (alcaline batteries) DC ? LM317 works only with >3 V my 650nm laser diode needs 2.1-2.5V and 18-25mA. Thank You

Is it possible to measure Laser output power with Temperature Sensor ? eg. datasheet: http://www.gme.cz/_dokumentace/dokumenty/313/313-909/dsh.313-909.1.pdf I have seen Laserbee LPMs and LPM based on IR thermometer and piece of aluminium foil, but what about to use Temperature sensor and...

Hi, where can I read if diode produces IR or any other light I dont want to? Wanna buy Laser diode and Datasheet shows only "red wavelength". Does it mean that no other wavelengths will be produced? look at this datasheet www.gme.cz/_dokumentace/dokumenty/511/511-270/dsh.511-270.1.pdf Thank You.

Hi, how to choose good goggles? Many sellers tell you only wavelength and price. But is it everything you need to know? if I buy glasses with correct wavelength (eg. I m gona use green lasers 532 nm, need to buy glasses for lasers 370-560 nm), does the power of my laser matter too? Does the...

I have heard bad reviews for Wicked Lasers (33 reasons why not to buy...), but they has realy good looking lasers... What do you think about their Core 5mW green laser ? (just want <6 mW with IR filter, on DX there are low priced lasers without IR filter...) Is there something bad on WL Core...

Hi, I have read many posts and articles about laser pointers (up to 200mW). I d like to ask you few questions because I am not sure if I understad to lasers enaught yet. (sorry about my English, I am from Czech) 1. IR and power in mW Can be said that laser beam is consisted of 2 different rays...
