QCW Linear Bar Array QD-Qxy01-A1 / QD-Qxy01-T / QD-Qxy01-H DESCRIPTION QD-Qxy01-A1, QD-Qxy01-T, QD-Qxy01-J, QD-Qxy01-H are conductively cooled laser single diode bars operating at high QCW optical power. The ‘x’ designs the wavelength window and ‘y’ characterizes the optical power of diode bar proposed up to 400W QCW (cf Table below). These products are based on an efficient and reliable 1cm linear bar arrays. Design is optimized to very high repetition rate (up to 50 kHz). Operation at high Duty Cycle and high average optical power is addressed with “H” package offering a low thermal resistance. An additional FAC lens is an option appropriate for application requesting well collimated beam (~8 mrad @ 1/e²). Assembly in a compact and rugged package (A1 or T) using AuSn hard solder allows building association of bars for dense pumping arrays for a wide range of applications.

ABSOLUTE MAXIMUM RATINGS QD-Q1401-A1 QD-Q1401-T Maximum duty cycle Pulse width Reverse voltage Operating temperature Storage temperature Maximum Duty Cycle: up to 20% on “H” package Note : Operation at temperature below dew point requests to use dry N2 environment PACKAGE SPECIFICATIONS - dimensions are in mm - standard tolerances are + 0.2 mm This “A1” package, with one diode bar, is a thin design (4.2mm) adapted for an integration in a small space. It is also well appropriate to realize a compact association for application which requests a long and quasi-uniform emission line.

This “T” package has been design for high compactness. It is also well appropriate for building a multi-bars compact emission line. This “H” package allows a very low thermal resistance (~0.4° /W) and is specifically adapted for operation at high Duty Cycle and high average optical power.
