레이저 다이오드 QCL

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

High Peak Power Source

Alpes Lasers introduces its new high peak power sources. Based on a unique gain-guided design, these Quantum Cascade Lasers are optimized for emitting short pulses from 20 ns to 1000 ns with minimum peak power of 20 W, or ~5 microjoules per pulse. Available on submount or in a HHL package with a dedicated driver, these lasers can be used for free-space optical communications, LIDAR applications and IR countermeasures.

You can read more about the technology behind these high peak power devices in this  Optics Express paper.

laser technology

The beam divergence of these lasers is much reduced in the horizontal axis compared to standard high power or low power devices. This is due to the unique large width of the active region of the gain-guided laser technology. Typical beam shapes are shown in the picture  to the right. Other wavelengths are also available with lower power, please write to us with any enquiry.
