The PulseLife G-stack from Coherent are Laser Stacks that operate at 808 nm. These vertically conduction-cooled lasers use Coherent's proprietary PulseLife hard solder technology to deliver Quasi-CW output powers of more than 200W/bar, a duty cycle of 4%, and a pulse width of 500 microseconds. They have high operating temperatures, with the reliability of over 109shots. The laser stacks are available in standard packages with 2 to 16 diode laser bars in a single stack. These laser stacks have a bar to bar spacing of 400 micrometers and require a threshold current of 30 A.
