got a cheepo green laser from ebay worked ok for about 10 minutes then went off now all i get is a fain red light from the tip any ideas
Just dont look into it. if you see a faint red glow, it means that the pump diode is still lasing at 808nm (just into the near infrared) most likely your crystal set or allignment is knocked out.piercedrab said:got a cheepo green laser from ebay worked ok for about 10 minutes then went off now all i get is a fain red light from the tip any ideas
