Abstrakt: A new high power AlGaAs laser with a window structure, crank type TJS laser, has been developed. The laser operates in a fundamental transverse mode even at 20 mW CW power. The threshold current is reduced to as low as 20 mA by shortening the crank length of the laser and the diode oscillates even above 80°C. The maximum power of the diode is nearly ten times higher than that of a conventional TJS laser. Maximum powers of 200 and 40 mW are obtained in pulsed and CW operation, respectively. Static characteristics of the diodes and interim status of long term operation are described.
