In order to develop a new type of airborne compact repetitive diode-pumped slab laser operating at -40℃~+65℃, a diode-pumped laser without thermoelectric coolers was adoped to overcome the problems of thermoelectric coolers. The experimental results show that the laser can work stably and reliably under the condition of -40℃~+65℃ environment at 20Hz~30Hz pulse repetition frequencies with laser output energy of 100mJ~150mJ and pulse width of 6ns~7ns. The beam divergence becomes 1mrad after passing through 4 telescope. The diode-pumped laser can be used in airborne and carborne laser rangefinders/designators.
