Pressure tuning of high‐power laser diodes in the 720–1540 nm range

Abstract

Laser diodes with output powers of 1–2 W and emission wavelengths of 808, 860, 975, 1060, 1120, 1210, and 1540 nm have been tuned with pressure up to 2 GPa. Pressure tuning might become a practical method for tuning near‐infrared lasers in spectroscopic applications, such as photoluminescence excitation, photoreflectance, and resonant Raman scattering, as well as in applications as optical pumps at unique wavelengths.

High Pressure Semiconductor Physics

“…From the more technological point of view several papers deal with investigations of laser diodes under high pressure. They arrive not only at a better understanding of the lasing mechanisms at work but also at practical applications, for instance, allowing for the pressure tuning of lasers in the 1 to 1.5 micrometer range [4].…”
