Injection Laser Diodes are electrically pumped semiconductor lasers in which the gain is generated by an electrical current flowing through a p–n junction or (more frequently) a p–i–n structure. Besides, due to the long lifetime of formed triplet excitons, the radiative singlet exciton population decreases with time while the triplet exciton population increase, which is called the triplet accumulation. Suppression of external quantum efficiency roll-off at high current densities in organic light-emitting diodes by efficient scavenging of triplet excitons. Both laser diodes and LEDs (light-emitting diodes) are used for this purpose, but the laser diode generates a smaller beam that is easier to couple with the smaller core of singlemode fibers. Laser beam is then available from the semiconductor region. Shitikov, I.A. However, relatively low Q-factors of optical Si microresonators demonstrated so far have limited some promising applications. Injection Laser Diodes are electrically pumped semiconductor lasers in which the gain is generated by an electrical current flowing through a p–n junction or (more frequently) a p–i–n structure. A fiber-coupled laser diode (LD) working at 795 nm was used to pump a Tm:YAP (diameter 5 mm × 9 mm) crystal with 3% Tm3+ doping. For optimal construction of such devices it is necessary to know the parameters of the locking mode, which is a challenging task. By using this triplet scavenging host material which has a faster rate of triplet relaxation, the triplets formed on emitter material can be effectively scavenged out (Figure 1).

When the emitter molecules were doped into CBP host, severe quenching of singlet emission observed even at 50 µs pulses and beyond 20 mA cm-2 current densities. The devices with CBP host showed a rapid EQE roll-off beyond 20 mA cm-2 current densities (Figure 3a). We observe that $\mathrm{MgF_2}$ microresonators feature quality factors that are very close to the fundamental absorption limit, as caused by the crystal's multiphonon absorption (Q$\sim$10$^{7}$), in contrast to near-IR measurements far away from these fundamental limits. Laser Diode Construction The above figure shows a simplified construction of a laser diode, which is similar to a light emitting diode (LED). The forward biasing done on the semiconductors used in the laser diode forces the two charge carriers (holes and electrons) to be injected or pumped from the opposite side of the p-n junction into the other side called the depletion region, which has zero charge carriers.
