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

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.
