Laser System Model 1101-46-HP-XXXX

Pulsed High Power Room Temperature QCL System

Specifications

Model 1101-46-HP-XXXX quantum cascade laser is supplied as a complete system consisting of the laser head with its matched power supply, ready to be turned on in a customer's location. The standard version of the system consists of the quantum cascade laser and its collimating optics, located in a hermetically sealed package for trouble free operation in harsh physical environments, plus appropriate electronics. The MWIR laser radiation emerges in a ~4 mm diameter nearly collimated beam.

For special applications, the system is available (at optional extra cost) with an external bayonet mount infrared beam expanding lens for projection of the MWIR beam over kilometer distances (see the photograph above, in which a Janos ASIO 50 mm F/2.3 objective is integrated with the laser head). The bayonet mount accepts other lenses for customer specific applications.

Output pulses are of fixed duration, user-specified between 50 ns and 500 ns, with frequency from single pulses up to 1 MHz. The system features very fast pulse rise and fall times of less than 5 ns. Various internal and external triggering options are provided.

The laser is offered in three pulsed power output versions:

Model 1101-46-HP-1000: Peak pulse power output of > 1.0 W in an ambient environment with laser head at room temperature

Model 1101-46-HP-2000: Peak pulse power output of > 2.0 W in an ambient environment with laser head at room temperature

Model 1101-46-HP-4000: Peak pulse power output of > 4.0 W in an ambient environment with laser head at room temperature
