Running an Endurance lasers in impulse mode. Max optical power output is 16 watt (second test).

 

 

 

An Endurance laser test 1.

Diode: NICHIA NUBM44 / NUBM47 laser diode @445 nm.
Average optical power on calorimeter: 1.25 watt
Laser diode voltage: 5V
Laser diode current: 7A
Duty ratio 12.5%
Frequency – 250 Hz
Pulse duration – 0.5 ms (1/200) sec.
Optics – no lens.
Max power (Average/Duty ratio) 1.25/12.5% = 10 watt.

 

An Endurance laser test 2.

Diode: NICHIA NUBM44 / NUBM47 laser diode @445 nm.
Average optical power on calorimeter: 2.05 watt
Laser diode voltage: 7,07V
Laser diode current: 8A+
Duty ratio 12.5%
Frequency – 500 Hz
Pulse duration – 0.5 ms (1/200) sec.
Optics – no lens.
Max power (Average/Duty ratio) 2.05/12.5% = 16,4 watt.
