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 when i power it up continuous for 1 day.
My questions are as following
(1) Will intensity reduce in every LASER diodes if i power it up continuous for long time say 15 days at constant current ?
(2) Suppose i have laser diode rated at 5000 Hour life span and i power it up by 50% duty cycle PWM will it increase it life?
I want to use LASER in security system so i will remains on continuously.
Looking for suggestions and advice from you!!
