Hello all at PL. LTNS and hope all are doing well!
Can anyone help me to diagnose the fault with this 500mW DPSS laser please? It does it's usual power up sequence and begins lasing - maybe a few milliwatts for around 10 seconds, then stops. The power supply then gives some weak beeps. I turn it off and try again and it fails to output, unless I leave it to cool down.
Does this sound like a dead diode or electrical fault (TEC or Thermistor). Any guidance appreciated please.
