Laser diodes for spectral range 2.7-3.8 mm are mounted on LA-type open packages which are necessary to be placed in cooling system. Operating temperature range for our 2.7-3.8 mm Laser Diodes is 30-100 K in CW regime and 30-150 K in pulse regime. Using laser structures based on III-V solid solutions gives us many advantages in comparison with laser structures based on lead salts due to fundamental characteristics of III-V materials - higher power, higher spectral purity, higher reliability and longer life-time.

Earlier lasing frequency was usually tuned only by heating. Besides this quite slow process our tunable diode lasers for spectral range of 2.7÷3.8 mm providecurrent controlled wavelength shift about 0.5¸1.0 cm-1in single-mode lasingtowards the shorter wavelength based on nonlinear optical phenomena.
Laser diode Models in which super-fast current tuning is available are marked with letters “tun” - for example model LD331-tun-LA. Other models (for example LD331-LA) can be tuned by changing the temperature.We are also offering Laser Diodes mounted in a small dewar. In this case model is marked with letters “DW” – LD331-DW or LD331-tun-DW.Standard Models LDXXX-LA and LDXXX-tun-LA are made from narrow-stripe laser structures and have average power about 1 mW and single longitudinal mode structure (SLM) that means that at determinate current and temperature range main mode is stronger then common intensity of other modes.
