Current is about 1mA approx.as we are using 10% tolerance resistor so current may vary some what .... Yesterday I read on Internet that such cheap cost modules made using bad semiconductors so it may cause shorter life and reduced optical output with time ... What about PWM based operation of...

Yes exact this diode ....driver is connected extranally custom made .I don't think it has in built driver.actually it has single resistor in case. What is your opinion on pwm Base operation of such diode ?

Hello All Members I am quite new in field of LASER. Recently i have bought 5mW Red LASER from local market (Cheaper one).I have attached photo of it. I am powering it with constant current power supply made by LM317. I have noticed that at ambient temperature LASER intensity becomes 50% less...
