The performance of a 665-nm GaInP disk laser operated continuous-wave at
15 degrees C both in-well-pumped at 640 nm and barrier pumped at 532 nm
is reported. The efficiency with respect to the absorbed power was
enhanced by 3.5 times when using a 640-nm pump instead of a 532-nm pump.
In-well pumping which is based on the absorption of the pump photons
within the quantum-well heterostructures of the gain region instead of
short-wavelength absorption in the barrier and spacer regions reduces
the quantum defect between pump and laser photon and hence the heat
generation. A slope efficiency of 60\% with respect to the absorbed pump
power was obtained by in-well pumping at 15 degrees C. Continuous-wave
laser operation was further demonstrated at heat sink temperatures of up
to 55 degrees C. Both the measurement of photoluminescence and COMSOL
simulation show that the overall heat load in the in-well pumped laser
is smaller than in the barrier-pumped laser. These results demonstrate
the potential of optical in-well pumping for the operation of red
AlGaInP disk lasers if combined with means for efficient pump-light
absorption. (C) 2015 Optical Society of America
