Femtosecond lasers
INDYLIT 3
Ultracompact Femtosecond Laser for Ophthalmology
The Indylit 3 is an ultra-compact femtosecond laser with moderate average power and pulse energy, optimized for ophthalmology applications such as the SMILE procedure. Laser offers excellent pulse and beam quality, which, along with its robustness, makes it the perfect choice for ophthalmology applications. The laser head is highly compact, lightweight yet robust, and has very low heat dissipation (~10W). It is also dust and water protected (class IP51) and operates within a broad temperature range (15-40°C) and has an integrated pulse-picker, making integration simple even in the most tight and demanding environments.

1) Laser power is approximately constant in the 1-5MHz operation range. Pulse energy is therefore inversely proportional to the repetition rate.
2) Attenuation can be controlled by a few different methods: a) by PC user interface, b) by CAN register, c) by analog input (0-1V, rise time <1μs). Beam quality specifications are maintained down to 10% power level.
3) Defined as the worst case ellipticity along the z-scan (± 5 xLRayleigh) of the beam.
4) Measured during 8h operation starting 30 minutes after cold start. Environmental temperature stability within ± 1°C.
5) Measured with integration time of 1s at the same conditions as (4).
6) Measured within 10s time interval for at least 1000 pulses.
