7) Laser operating mode and laser service life.

The attached graph shows the dependence of lifetime on diode temperature. It refers to the red diode with resistance -12~45°C. Please take it as a guideline. It is not just a direct laboratory output, but also our practical experience.

Almost all red industrial lasers are designed for continuous operation. However, lasers with DC/DC converters are the most suitable because they heat up the least by their own operation. For models where this is not the case, this is stated in the technical specifications.

However, each laser has a certain number of hours it should be able to operate before the laser diode burns out for good. Usually this is more than 5000h of lifetime at temperatures around 20°C. Temperature is the key to long laser life! Generally speaking, lasers are comfortable at room temperature. Where it is good for man, it will be good for laser (see paragraph 5).

Lasers do not mind being switched off and on at all in terms of their normal lifetime. They can handle more than 1,000,000 cycles. Some models can cycle at 100Hz. And some even 100kHz, so they can handle a lot more than that million cycles. So we recommend turning them off unless you need them lit. You'll significantly extend the life of your laser because it won't wear down as much with heat.
A laser can be compared to a candle. It can also be lit 1000 times, but it doesn't do much for the life of the candle when lit.

Temperature and lifetime dependence for green HT lasers.

This chart is for the green diode HT lasers we use for the tempered laser models. The chart does not take into account the tempering.. just the operation limiter that disconnects the laser diode if its temperature exceeds the set limit.
