Semiconductor Lasers

TO package including the TEC can be used for optical powers of >10 mW.

Progress Towards Development of Low Power Consumption Lasers for Planetary Atmospheric Studies

MDL has demonstrated single spatial-mode ridge waveguide semiconductor diode lasers operating continuous wave up to 60C in the 3 μm wavelength range. The fabricated lasers operate in CW mode at room temperature with output powers exceeding 5 mW and have power consumption of less than 0.2 W at the output power of 1 mW (sufficient for many spectroscopic applications).
