레이저 다이오드 QCL

양자 폭포 레이저(Quantum Cascade Laser)는 중적외선 범위에서 빛을 방출하는 광원입니다.

THz Lasers

Terahertz quantum cascade lasers are operating in the range from 1 to 5 THz. Coherent polarized THz radiation is generated as a result of direct stimulated optical transitions of electrons within the conduction band of a semiconductor heterostructure.

All THz lasers require cryogenic cooling. Alpes’ QCL can be shipped in one of three different options of cryogenic cooling hardware, or can be shipped as CoC if you can provide your own cooling solution.

Specifications

Pulsed Multimode THz QCL are currently available at the following wavelengths:

 

 

Central Frequency Central Frequency Peak Power
1.3 THz 45 cm-1 > 0.1 mW
1.8 THz 60 cm-1 > 0.1 mW
2.3 THz 78 cm-1 > 0.5 mW
3 THz 100 cm-1 > 5 mW
4 THz 133 cm-1 > 5 mW
4.7 THz 160 cm-1 > 1 mW


 

For these lasers peak power is measured with 200 ns pulses at 1% duty cycle and a temperature of 10K. Some lasers can also operate at 77K or higher temperatures with reduced performance. The spectral output is multimode and can vary in a range of 10% around the central frequency.
