Abstract
Semiconductor lasers are susceptible to harmful high currents or high voltage electrical transients. Semiconductor pump lasers are especially vulnerable to electrical transients under normal operation because of the large continuous wave current needed to drive the semiconductor pump laser to achieve a high optical power. A protection circuit for 980 nm pump lasers using a non-linear voltage-dependent resistance means which limits drive current based on a drive voltage powering a laser diode is demonstrated to be effective in guarding the laser against harmful electrical transients.
