External cavity Tunable Laser Source

TLS-APX series tunable laser sources are high performance external cavity Littman tunable lasers combining wide tuning range, high output power and high signal-to-noise ratio. Different wavelength ranges are available between 1040 nm and 1650 nm. The TLS can be connected to several APEX Technologies equipments based on interferometric principle (OFDR, OSA, OCSA). Tunable laser sources OEM and stand-alone benchtop instrument versions are available. The TLS benchtop instrument is proposed with a friendly-user software, a touch sensitive screen, GPIB, ethernet controls.

TLS Narrow linewidth : 280 kHz for 1s integration

APEX Technologies TLS provide a Narrow linewidth. By using a Self-Heterodyne measurement technique, with 600 m delay fiber, we measured a linewidth of 280 kHz for 1s integration time

Low Noise Operation: RIN<- 140 dB/Hz

APEX Technologies Tunable Laser Source provide an excellent power level stability. We measured a Relative Intensity Noise better than -140 dB/Hz at low frequencies (< 500 kHz). At higher frequencies (up to 500 MHz), the laser RIN is limited by the shot noise level (-158 dB/Hz)
