Laser diodes have the same reliability and failure issues as light-emitting diodes. In addition, they are subject to catastrophic optical damage COD, when operated at higher power. Many of the advances in reliability of diode lasers in the last 20 years remain proprietary to their developers. Reverse engineering is not always able to reveal the differences between more-reliable and less-reliable diode laser products.
