WebThe laser module for this design is a 975nm pump laser, with 250mW output power. Laser modules require drive currents in the range from 300mA up to 3A. The particular laser used in this design requires a minimum threshold current of 35mA to operate, and can be driven up to 500mA when achieving maximum power output. Thermoelectric Cooler (TEC) WebWe investigated amplification with a 50 mW, 7 ps : Nd: YVO 4 oscillator, a 2 mW, 15 ps Yb fiber laser, and a 30 mW, 300 fs Nd:glass laser. Output power as high as 9.5 W with 8 ps pulses was achieved with the 250 MHz vanadate seeder, whereas the 20 MHz fiber laser was amplified to 6 W.
Semiconductor optical amplifiers (SOAs) are amplifiers which use a semiconductor to provide the gain medium. These amplifiers have a similar structure to Fabry–Pérot laser diodes but with anti-reflection design elements at the end faces. Recent designs include anti-reflective coatings and tilted wave guide and window regions which can reduce end face reflection to less than 0.001%. Since this creates a loss of power from the cavity which is greater than the gain, it prevents the …
