It is said to meet the demands of high-resolution laser-spectroscopy users (in the configuration with a DFB laser SPECDILAS-Q-MTE). But it can also be used with an FP laser QF-1810-TMP-MTE as an IR adjustment laser to activate specimens, or for detector testing. For many experiments, it serves as a handy high-performance alternative to CO2 lasers. Temperature, pulse flow, and duty cycle are factory set but can be reset by users.
