“…Figure 5 shows the current dependence of slope efficiency (SE) at 15 °C. The maximum SE is 0.96 W/A, which is comparable to that of other reports [19][20][21][22]. In spite of the ordinary value of SE, the high power density is the result of suppression of roll-over phenomena by the nonzero-detuning (|λ gain -λ cav | ≠ 0) at the threshold as mentioned above [18].…”

“…In literature internal temperature is determined by comparing continuous wave laser characteristics (output power , laser voltage or emission wavelength ) with pulsed measurements [2] or from an estimation of laser thermal resistance [3]. A pulsed measurement requires a broadband measurement setup which is not available for all wavelengths and also has other disadvantages.…”
